I have over 3" of lift, from 4 door springs, raised spring pad, strut spacers, and jeff's spacer. Had to lower the diff, to keep CV's intact. I ran out of strut travel, and either need longer strut spacers, or OME struts.
If I started over again, I would chop and drop the frame in front and back. Then all the IFS is in stock position, steering not an issue. You could still use 4 door springs for another inch + of lift. One added benefit of the frame drop would be that it creates more space under the oil pan in case you wanted to center the diff. The motor has to be raised anyway to keep the transmission mounts (and motor position in the body). I would include a strut brace in the mix, to help the struts and prevent any frame flexing. I am supprised that we don't see more frame drops.
