A little bit of lift on the cheap-

People give away stock springs, and you can probably score some ZJ V8 coils, or, if not coils, some coil spacers, for not much money. Make your own clamps, get some new Ubolts and centering pins. If you're worried about the shocks being too short (on a DD at 1.5-2", I wouldn't be), you could get some BPEs for relatively cheap, or make some using the rear sway bar parts and some new hardware. That gets you back about 3/4", and saves you having to fight with the shock mounting hardware again in the future.
I've been really happy with Bridgestone's Dueler ATs- ran the older style on my stock wheels for a few years, and am running 16" Revos now. I think they set me back about $100 per corner for 235/75/15s. A friend runs some Goodyears on his, which he got some right around $85 installed. But, tire prices vary widely, and IMO it's definitely worth hitting the smaller shops. A little independent outfit set me up with the Bridgestones for less than anyone else would have installed their generic passenger tires. And there's always the used/takeoff route. I know some people won't run used tires, but I've had good luck with all of mine.
