In terms of solving the bottoming out issue, short of getting the Add-a-Leaf or replacing the springs with something from Deaver, Alcan, or the like, probably the best thing is the spacer/shackle lift.
PRG and
Nisstec both offer these at a very reasonable price (Nisstec's is an add a leaf style). They're easy to do - maybe an afternoon of tinkering if you're not in a hurry. The only real issue you might run into is needing the camber bolts up front and/or the shims for the rear. I needed neither, for some lucky reason.
Worth noting, though, is that Nisstec's
Airbag package isn't much more than the 2" lifts.
