whats the difference between a Supercharger and Turbo ?
Turbos run much hotter since they are powered by the exhaust. In this application the ECU actually doesent know there is a differencec between the two.

whats easier on the motor ?
The turbo uses waste energy to spin so there is no direct drag on the pully system to run it.

whats gives more power ?
Because there is no drag on the engine turbos (if sized correctly) typically make slightly more HP per pound of boost. You dont have the instantanious responce of the supercharger though. Basically, you trade instant torque for more total HP

whats easier or cheaper to install ?
TURBO is less costly without a doubt. Unless you find a very good deal on a used supercharger. Again this is a trade off. Installing a turbo requires more work and perhaps fabrication depending on what is included.

do you have to run Premium fiel with the Turbo ?
Absolutely, its just like a supercharger. I would also reccomend 1 step colder spark plugs.

about how much would the Turbo cost ?
Depends on the turbo. Junk yard turbos can be found for very little. Supra A turbos from the 3.0L MK3 supra are available for well below $300 including the wastegate actuator and oil lines.

and, "about" how much more power over stock will this have ?
I had about 260 out of my last setup but that was with an intercooler running very mild boost. With the correct supporting mods there is no reason that this kit couldent WELL beyond that. 300 would be attainable with fuel mods and an intercooler.
