what size tires are you planning on running, are you going to modify the fenders any? stock axles? re-gearing? i personally would recommend 33" tires max and a 4" lift max. tires bigger than that wont fit in the wheel well (33's will even rub a little) and over 4" of lift ruins the geometry of the TTB front end and will cause it to bind unless you move the bump stops down (therefore defeating the purpose of lifting it in the first place, imo) although you may be able to purchase cut/turned beams and help with this problem a little.
you should also plan on lowering you're axle gear ratios, if you're going to run a tire 33" or more.
and i would stay away from a body lift, not only do they look stupid, they have a tendency of breaking, coming loose, among other problems. plus they dont gain you anything except wheel-to-fender clearance (no added travel or ground clearance etc)
....unless of course it's for mall crawling or some other kind of lameness, then by all means, run 36's, and lift it like a foot using blocks and body lifts ewwww..
