It's not that simple. Someone will have to do it for you. Prices have been stated previously

Yes, but you can't just pull the 3.73 gears out and throw in 4.88's. They have to be set-up correctly, which requires special tools and knowledge.

well whats the difference between 4.56 and 4.88 gears? my old shop teacher did the math and conversions and told me that a 4.56 would get me close but just a little lower than stock keeping the 35 inch tires that i have

With 35's you'll want 4.88's. You also have to account for the increased weight/rolling mass, increased drag, etc. Conversions done on paper or online don't account for this.

They will probably improve mileage some. But my guess is that you haven't accounted for difference in tire size when figuring the mileage anyway.

Well here is another question what can I do to beef the front up the bumper I'm making will be anywhere around 200-600 pounds what will need to be done with the suspension to help support that weight? I'm new to this and I'm glad that I have someone to ask so that I'm not doing it all on my own, any sugestions?

It doesn't have to be insanely heavy to be strong. I had a very strong tube winch bumper on my Ranger, probably 150lbs or so. Heavy? Yes, but nowhere near 600lbs. I didn't end up having a winch in it, but either way I wouldn't make the whole combination more than 200lbs.
I didn't do anything other than running bilstein HD shocks and the torsion bars were adjusted slightly (not "cranked").
