What are you looking to spend? I'd probably go with the RE 3.5" kit with the full leaf springs because it includes lower control arms. Get yourself a decent double shear track bar (IRO for a cheap one) to center the axle. That should get you enough lift to clear the 32's with flares and the heavy bumpers. I had a Rusty's 3" lift with full flares and 32's that I DD'd and lightly wheeled.
32's and 4.56 gears are awesome on the road and trails, just FYI
