I would get the 33's, no point in buying bigger later to replace a decent set... and then make plans to re-gear. this also opens other doors... upgrade axle now and ditch the D35 (if thats what u have) and maybe a lunch-box locker too.... i know your in CO but I would sell you my 29 Spline 8.25 3.55 axle (would give you the front but its LP and a down grade for you) for 50$ and a 12 pack, once I have my axle swapped. deals are out there.. even for D44's and already re-geared axles...
example- my D44 front with upgraded shafts and 4.56 cost my a total of 180$, the rear 8" Toyota with an e-locker cost me 3 hours of trade work... thats cheaper the re-gearing my stock axles alone.
IMO
31's-ok
32's-manageable
33's-at least 4.10's in the long term.

in short. get the 33's and start saving and looking for deals for gears/axles....

*edit- going from a 31, to a 32 is not a big difference and will leave you wanting more...
