If this is a regular incandescent fixture, the manufacturer probably just used white wire for cost reasons.
Before you connect the fixture's wires you should take a close look at the fixture and make sure that the wire that goes to the shell of the bulb socket is connected to neutral wire (usually the white wire in the ceiling box) and the wire that is connected to the center of the socket goes to hot (usually the black wire in the ceiling box).
If this is a fluorescent or hid (metal halide or sodium vapor) lamp fixture, please consult the directions or contact the manufacturer for installation instructions.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.
IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS

No, the black wire from the ceiling fixture should be connected to the combination wire of white and grey. The white wire from the ceiling fixture should be connected to the yellow wire. Always follow the manufacturer's instructions and turn off power before making any electrical connections.
A three wire fixture most likely is one that has two separate loads within it. An example is a ceiling fan with a light fixture. If the three wire is used to separately switch the two loads you have to make a decision as to which load you want to work with the two wire fixture. Once that decision has been made connect the two wire fixture in parallel with the your selected load on the three wire fixture. On these types of installations the three wire fixture is usually controlled by two separate switches in a two gang box. The red and black wires of the three wire terminates on the bottom of either switch. The white wire is connected to the incoming neutral. The top of the switches are paralleled together with the "hot" feeder from the distribution source.
By earth wire I am assuming you mean the bare wire and that a black and white wire are connected to the light. If when you connect the earth wire and breaker trips then there is a short between black and earth. It could be a bad ground connection, an internal short in the light fixture where black wire "hot" is connected to metal on the fixture through a nick in wire.
You switched the power and switch wires. There should be two sets of wires in the ceiling box. 2 black, 2 white, 2 bare. Two groups of three. The white wire going to the light is the incoming wire. The black one in that group is the power coming in. Take that black wire and connect it to the other black wire. The second black wire goes to the switch. The power comes back to the light on the white wire of that set. Connect that white wire to the black wire in the fixture. The switch should work now. That is if everyone wired the house the way it is supposed to be.
You would have to provide more info to be certain what your problem is. Typically a black and white wire would connect to the two wires on the light fixture. The fixture should also be controlled by a switch that "breaks" the black (Hot Wire) to turn off the fixture. If you have a volt meter you can see if there is 120Volts between the black and white wires with switch on. If there is a single white wire going to fixture (Neutral), where is the "black wires tied" to. Maybe one of the black wires has broken off the fixture.
To install a ceiling light fixture, first turn off the power to the fixture at the circuit breaker. Remove the old fixture and disconnect the wires. Connect the new fixture's wires to the corresponding wires in the ceiling, usually black to black, white to white, and green or copper to the ground wire. Secure the fixture to the ceiling and turn the power back on to test the light.
No, the black wire from the ceiling fixture should be connected to the combination wire of white and grey. The white wire from the ceiling fixture should be connected to the yellow wire. Always follow the manufacturer's instructions and turn off power before making any electrical connections.
This question isn't clear.
To install a light fixture in the ceiling, first turn off the power to the area. Remove the old fixture, then attach the new fixture's mounting bracket to the electrical box in the ceiling. Connect the wires from the fixture to the corresponding wires in the ceiling, usually black to black, white to white, and green or copper to the ground wire. Secure the fixture in place and attach the cover. Turn the power back on and test the light to ensure it is working properly.
To properly wire a ceiling light fixture, first turn off the power at the circuit breaker. Remove the old fixture, connect the fixture wires to the corresponding wires in the ceiling box (usually black to black, white to white, and green or bare to ground), and secure the connections with wire nuts. Finally, attach the fixture to the ceiling box and turn the power back on to test the light.
To properly install a screw-in ceiling light fixture, first turn off the power to the fixture at the circuit breaker. Remove the old fixture and disconnect the wires. Attach the mounting bracket to the ceiling box, then connect the fixture wires to the corresponding wires in the ceiling box (usually black to black, white to white, and green or bare to ground). Secure the fixture to the mounting bracket and install the light bulbs. Turn the power back on and test the light to ensure it is working properly.
The recommended ceiling light wiring diagram for proper installation involves connecting the black wire from the light fixture to the black wire from the ceiling, the white wire from the light fixture to the white wire from the ceiling, and the ground wire from the light fixture to the ground wire from the ceiling. It is important to turn off the power before starting the installation and to follow all safety precautions.
To install a new light fixture, first turn off the power to the existing fixture at the circuit breaker. Remove the old fixture by unscrewing it from the ceiling and disconnecting the wires. Install the new fixture by connecting the wires to the corresponding colors (usually black to black, white to white, and green or copper to the ground). Secure the new fixture to the ceiling and turn the power back on to test the light.
To properly install a 3-wire light fixture in your home, follow these steps: Turn off the power to the circuit at the breaker box. Remove the old light fixture and disconnect the wires. Connect the black wire from the fixture to the black (hot) wire in the ceiling box. Connect the white wire from the fixture to the white (neutral) wire in the ceiling box. Connect the green or bare copper wire from the fixture to the ground wire in the ceiling box. Secure the wires with wire nuts and mount the fixture to the ceiling. Turn the power back on and test the light to ensure it is working properly.
To install a ceiling light using existing wiring, first turn off the power at the circuit breaker. Remove the old light fixture and disconnect the wires. Connect the new light fixture's wires to the existing wires, matching the colors (e.g., black to black, white to white). Secure the fixture to the ceiling and turn the power back on to test the light.

To install a new light fixture in a room, first turn off the power to the existing fixture at the circuit breaker. Remove the old fixture by unscrewing it from the ceiling and disconnecting the wires. Next, attach the mounting bracket for the new fixture to the ceiling box. Connect the wires from the new fixture to the corresponding wires in the ceiling box, usually matching black to black, white to white, and green or copper to the ground wire. Secure the new fixture to the mounting bracket and install the light bulbs. Finally, turn the power back on at the circuit breaker and test the new light fixture to ensure it is working properly.
