Yeah the body lift in itself wouldn't be enough to steer me away from purchasing. Just make sure that with it off, the jeep will still be in good working order. Tall body lifts may require extended brake lines, fuel filler hoses, modified steering, etc etc. Things like that can make it a real pain for you.
x2 on toolin around's point, but chances are with a long arm kit, it's probably already high enough to clear the tires, but you have to be sure.
You could always install a smaller size body lift as well. They're relatively cheap and if you're taking one of already it wouldn't be that hard to swap out a smaller one.
