4.10 and 33" tires will have your RPM right around where they generally are with stock size tires/gears. 4.56 will bump you up a couple hundred from stock at freeway speeds, in O/D. Really not much of a change, but, my guess is, gas mileage will suffer a bit on the freeway, but, you will have MUCH better low-end grunt. Should be able to pull the house off the foundation with the right tires.

Here is an online calculator. (all the way on the bottom.)
O/D Ratio is .69
T-case ratio is 1
With 33 inch tires, and 3.55 gears, 60 mph is just under 1500 RPM.
Same tires with 4.10 gears is 1730 RPM
with 4.56 gears is about 1925
In my opinion, 1500 is just too low. The engine is lugging trying to hold speed, even a slight hill will make it downshift.
1700 or so is actually pretty good.
1925 might be a bit high. You would be running about 2500 RPM at 75 MPH.
