because of your budget, i would say the RC 3.25
with the zone 4 inch, you will also need adjustable rear uppers, an sye, and new driveshaft. maybe not at first, but eventually.
also, just the RC 2.5 lift would get you good clearance to run 33s. plenty of people run a 2.5 lift and a 1.25 BL with 33s and are pretty happy with it
