I wonder how 4.56's would be with 37's on that truck...or if it's even needed on that engine/trans setup.

Both reasons

If it were me, I would be putting in a front locker and swapping the gears for the 37s. I would at least use 4.10s and you should be able to find a good deal on them as several 03-07 H2s have changed out their gears and will have the 4.10s to sell cheap. I have a set you can have for $100 plus shipping.
