The 30/36/6.5 rule applies. 30" clearance side to side, 36" clearance in front of the panel, and at least 6.5' clearance in height. Now, saying that I would call the local inspector and see what he says. He has the last word and even though the national code does not specify any other requirements, best to let him tell you his requirements. IMO, the farther away from the sink the better.

You must have a switch to turn the disposal on and off. If you are asking how to connect because you do not have a switch. Install the switch under the sink just above the door opening. You can buy disposals that turn on and off when you place the lid over the hole. InSinkerator makes one.
There is no requirement on the distance the dryer must be from a sink. Any 120 volt outlet must be GFCI protected if it is within 6 feet of a sink. There is no requirement for a 240 volt dryer outlet. I would not want the dryer right next to the sink and I would want the dryer to be on a 4 wire circuit and not a 3 wire circuit. Use common sense here.
Are you referring to the original Intel 8051, or one of the many variants? The 8051 has weak internal pullups on the i/o pins, and can source only about 60 ua, but can sink 1.6 ma, still not much when it comes to driving the led in an opto. Some 8051-based dervatives can sink much more current. Atmel's 89C2051 for instance, can sink up to 20 ma per i/o pin. This can directly drive most optos.
A heat-sink is needed to dissipate the wasted power without any undue temperature rise. The effectiveness of a heat sink is measured by the watts dissipated per degree of temperature rise.
A source driver applies voltage to a ground (common)-referenced load. A sink driver grounds one side of a load which is already connected to the supply voltage. Given the same family of drivers, sink drivers generally have the greater current drive capability of the two.
