Yes
If you are referring to a switched UK-style socket outlet fitted with a led, or a wall switch fitted with a led, then the led merely indicates that the socket outlet switch or wall switch is in the 'on' position.
You can if you have a neutral wire present. If the existing switch is what is called a "switch loop" then you can not change the existing switch to a switched outlet. You can identify a switch loop by looking at the wires coming into the switch bow. If there are only one set of wires usually a black and white and they go directly to the switch then you have a switch loop
Most switched outlets have one half that's hot all the time. If that's the case it will be as easy as changeing the outlet. In the center of each side of the outlet there is a small piece of copper connecting the two screws. Look and see if the copper piece is broken on the hot side, if it is then replace the outlet using the constant hot. Cap off the unused wire from the switch. If both sides of the outlet are switched then you can remove the two wires from the switch and tie them together. then either replace the switch and have a dummy or put on a blank cover. You should be all set.
If I am reading your question right, you can do this. Just parallel the outlets to the device already switched by the 3-way switches. The outlets will turn off and on by the switches. Watch that you do not overload the switches or the circuit.
Could be a loose connection somewhere, or a bad switch, or a bad outlet.
There is no switch on an outlet. You can mount an outlet with the ground up or down. Most electricians I know mount the ground down as I do.

Yes you just have to "steal" power from the switch. Do this by running a pigtail wire from the hot of the switch to the hot wire of the plug. Make sure you do this before the switch or you will end up with your outlet being switched as well.

an off-load device a a switch where there is no current passing through it when its switched, a isolator is a off load device, a light switch is a on-load device because there is current passing through it when its switched.
You can make music come on with a light switch the same way you can make a light bulb come on - plug a radio into the switched outlet.
A typical duplex outlet has metal tabs on the sides that connect the twooutlets and a pair ofwiring terminals (hot and neutral)for each outlet. If you break off these tabs, you can power the two outlets individually. The circuit for the one you want switchedgoes through the switch to the terminals for that outlet. Run the hot wire to switch, the hot wire from switch to hot terminal of outlet you want switched, and neutral wire to neutral terminal of outlet you want switched. Run hot and neutral wires to the appropriate terminalsfor the other outlet.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 appliancesalways use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

See: "How can you re-wire a wall switch that controls an outlet to control a ceiling fan?" (Follow the link below.) The procedure is the same whether the new device is a light fixture or a ceiling fan.
In order to be billed for electricity, you have to have a flow of current. your electric meter is not unlike your water meter in this regard, it measures flow rate through it. An outlet that is not plugged in to anything that is on, or an empty socket that normally holds a bulb will not pass current. That means they are technically off. All a switch does is open an electrical circuit. To close a socket circuit you need a bulb. To close an outlet circuit, you need an appliance that is on (another switch may be involved).
Uh, because you left the switch on for what you had plugged in to the outlet.
