I've got 16" 2.5 Ballistic Hybrids with 7" shaft at ride height, 300lb over 400lb coils up front & 200lb over 300lb coils in back, 265psi in front shocks & 215psi in rear shocks. Of course it weighs around 8500lbs.
I'm running the same legth coilovers as you with the same amount of extention and compression that you mentioned. They are on what's left of a TJ with the same front and rear ends as you with the 4.0 NV3550 a 231/300 doubler and lots of tube. I'm running 150 over 200 in the front and 100 over 200 on the rear with 180psi of nitrogen. Seems to work good for my setup.
In the rear of my full bodied YJ, although 14" shocks, 6" up 8" down. 170 over 250. My YJ is fairly heavy, I think we figured on 750-800 lbs per rear corner, IIRC
