I'm about to do this myself. I'm getting the Ultimate TJ/LJ Kit from dirk at DPG Offroad. That is the 2 1/2 inch OME lift plus a 1.25" JKS body lift, which you'll need for 33s. I plan on regearing to 4.56 in the near future after the lift/tires/wheels are installed.
Also, I plan on going with the heavy coil rates as I'll have a full size spare on a carrier on the back and a winch out front.
