That is a lot of weight to get rid of. If you want looks, go w/ 18s. If you want performance, go w/ the lightest 16" you can find.
Exactly. The further removed from the engine you go, the less mass matters. And as far as wheels go, air weighs less than metal, especially the further out from the center of the wheel that you go (rotational mass).
