Garage Sub Panel

I just got done building a garage and now I want to get it wired. The sub panel in the garage will be about 100 feet from the main 200 amp panel in the house. I plan on using a 100 amp sub, and I am wondering what size of wire I need to use to conect the main panel to the sub panel. In the future I plan on making it into a work shop to do wood working etc. I will be the only one useing the shop and once in a while there might be two people working in there. The garge is about 1100 sq feet and I plan on heating it with LP and some day having air in it, most likely about 8 lights at 100 watts, and the other normal outlets.

100-amps (if you really need that much) will require three #3 or larger copper THWN (hot, hot, neutral) plus a #8 or larger copper ground, buried 18" deep in 1.25" or larger PVC conduit.
