May not be of much help, but with 4.88's I'm running 2700-2900 RPMS at 75mph with 35's.

I dunno...low 2000's? I normally drive around 75mph.

It's kinda odd. I had stock gears with 32's and got like 13mpg. I put the 35's with 4.88s on and i'm getting a good 15-17mpg now. That, and not NEEDING to go into 4LO is pretty nice when off road.

go with 4.56's, I just re geared mine with only 31's nowing that I am getting 33's in a couple days and the new ratios are a night and day difference. A little high in the rpm range right now because I only have 31's but when I get the 33's they will be spot on im sure.
