For 32" tires you don't need a body lift. Especially if you won't be flexing hard or rock crawling. You just don't need to raise the body on a dirt road.
You see the kits listed as 2" kits because big distributers like Q-tec have thier lifts grouped by size and it's closer to a 2" lift than it is to a 4" lift.
With a short lift you don't need new control arms and typically the driveline angles don't change enough to need adjustment, but don't spend all your budget as you never know what your Jeep will require. Chances are though the OME kit will be complete for you.
