I would look for another shop rather than do it yourself. You can't think of camber, caster and toe as independent settings because suspension and steering geometry is such that modifying one usually affects the other two. If it weren't for tolerance ranges in the specs, alignment would require several iterations. If you adjust camber using a level gauge, for example, expect to affect caster.

Are you sure uneven tire wear wasn't caused by a fault in the wheel bearings or suspension components?
