The suspension is pretty easy on those (for a 2"), you need some coils for the rear and upper control arms for the front, new shocks all around. Body lifts work pretty well too because Nissan welded all the body mounts lower on the frame on Pathfinders of that vintage when compared to the Hardbody pickups.
Check out AC www.4x4parts.com and Calmini www.purenissan.com for some parts and ideas. There are quite a few of us Nissan guys around, definitely join up on NOAS
