I would not do a 3.5 lift to run 33s. Not just because of appearance (if it is your Jeep and you like the big lift littler tire look-that's your right) but because once you get at the 3 inch lifts, you open up a whole host of other spendy issues because the geometry gets all out of whack. I would come down to a 2.5 lift. You technically can run 33s without a lift at all and maybe just trim the fenders but I would still do one (just because that's me). Or could just do a body boost instead of messing with coils if all you want to run are 33s.
And if you plan on any offroad, "pretty wheels" will not stay pretty. If just a DD, different scenario. So just keep that in mind.
