The ONLY thing that is going to gain you ground clearance is bigger tires, to fit bigger tires the easiest and cheapest way is a body lift...plus a body lift actually moves the body up higher so there is less chance of damage when wheeling.
If you know you want a SAS forget the IFS lift completely, spend the money on a Dana 44 now and start building it with gears/lockers/new u-joints etc.
Or spend the money on t-case gears, there is little else out there that gives you more bang for the buck and helps compensate for the larger tires offroad.
