If you want a great highway ride, look at the AEV 2.5" lift. I hear it is fantastic on the road. And still very capable off-road. At 2.5" of lift, 35's (or 37's with flat fenders, and a bit more upgrades...) would look great on it.
As said before, 33's give it an aggressive look, and do not take much $$ to make it happen.
