So you want to go with a wheel/tire combination that has a larger overall diameter than stock? Why?
Ok, you can do that with any size wheel you pick just by getting taller tires, but with 17" wheels you'll be forced to run a tire that's about 1/2" larger in diameter than stock.
16" wheels are a good option because you can get tires from just under stock diameter on up to whatever larger size you may want.
As far as wheel styles go that's just personal preference. I just got new wheels and I like them:
16" Enkei Or-52
