First, it's right at about the 4" lift height where you should install a longer CV (constant velocity) driveshaft and its required partner, a SYE (slip yoke eliminator) kit. The SYE kit gives more room for a longer driveshaft which is pretty much required to eliminate the vibrations a taller suspension causes from steepened driveshaft u-joint angles.
On the lifts you mentioned, I'd recommend something besides a Rancho brand lift. They always include those UBER-stiff R5000 shocks that are better suited for a tank than a Wrangler. BDS has a better reputation than Rancho. Another good brand to think of is Rubicon Express.
I would avoid a 15x10 wheel, a 15x8 wheel is actually better for a 33x12.50 or 35x12.50 tire if you plan on airing your tires down for offroading. Pretty much anyone offroading that size tire that is experienced will stick with 15x8 wheels. Think of it this way... it takes less air pressure to hold a tire securely against two edges 8" apart than two edges that are 10" apart so the wider the wheel, the more likely the tire is to come unseated when aired down on a tough trail.
Another thought is that 3" suspension lift plus the 1" body lift combination you mentioned. That's an outstanding way to get the 4" recommended for a 33" tire that eliminates the cost of the SYE kit and longer CV driveshaft. A SYE and CV driveshaft is always a good idea for 3" and taller but you can get away without it for a 3" lift more easily than with a 4" suspension lift.
Those are a few opening thoughts before I leave my office to leave for home, I hope they help a bit.
