welcome yj brotha, you're on the right track, get rid of the 3" body lift before it gets any where near your jeep.
i like the 4" rough country idea. the shackle reversal is kind of tabu. it is nice on the road, but guys i talk to that do it and wheel say it tends to unload on climbs and stuff. it does also stretch the front and improve approach angle.
personally i'd skip the suspension and body lift combo, jsut stick 4", just me. and if you're fairly new to wranglers i'd say do the lift first, get used to it and feel out what you like, then think about more advanced mods like shackle reversal. lots of guys do the shackle reversal w/ a spring over also.
