There are some pic's of my truck in my webshots in my sig.
I have 4" of lift and 36" tires. Most people like the rear to be a bit higher than the front...my tail sags a bit. I think you might be find with 4" front springs, trimmed "fangs", 4" shackle flip in the rear (or springs) and a set of 1" zero-rates to move the axle back some and get a bit more lift in the rear.
BTW with all the trimming and moving of the axle I have done my rear tires still rub! My front tires rub in the back but it isn't trimmed yet (and I have no travel up front because of the 4" rancho's).
