I would suggest the 4.10's for your set up. Most 2wd with 27-28" tires are pretty happy with 3.73's. With your 33" tires, the 4.10's will probably be just right.
I bought my last set up from Summit, and got Richmond gears. They do whine a little, but they are still pretty new. I assume they will quit down, if not I will re-set them.
Here's a nifty gear calculator to play with-
