I had a similar goal. First, I installed a Skyjacker 2" suspension lift (about $220). That's just coil spring spacers and shocks, so it doesn't require any drive train changes. I added 16x8 wheels (about $100 per, but you can get them for less) and 265/75 (31.5") tires (a little over $100 per). I was told this would be pretty high without sacrificing ride quality etc., and it seems the advice was correct. I also didn't need to regear (at least I don't think so...). To kick out the wheels a little, I also added 1.5" wheel spacers from Biff at Offroad Overstock (about $180), and because it looks cool, I put on a steering stabilizer ($35).
