If the TRD supercharger is anything like the one in the pictures I've seen it will be a roots type blower.
To address your question about oil for the SC, it depends on a lot of things. Some SC have sealed bearings and need no oil lubrication, others have external oiling methods that can be either a stand alone system, or a oiling system that is used in conjuction with the car's own oiling system. The later scenario is pretty rare. If the SC option is the latter type, then I would go synthetic, otherwise your car should be fine with normal oil. The only worry I would have about using synthetic oil in a SC engine would be the break-in period for the vehicle. During the break-in period your valve seats and and cylinder walls will be under serious stress, and the thinner sythetic oil might be troublesome for the rings to set up properly.
Finally, the colling off question... SC do not need a cooling off period like turbos do, because they do not deal with as high temps as turbos and they do not spin as fast so you do not have to worry about the impeller blades on the SC warping because you didn't properly cool them down.
