What gear ratio should i go with?

Well heres the deal, for now the 350 in the truck runs pretty good. I may buy a new motor for it this fall or winter or have one built. Something with some decent torque. Im not mud boggin all the time. but i do like to use the truck to play and pull stuff. Mainly i just dont want a dog of a truck off the line. Id like to get on it am it move, hop on the interstate and go to another town, just a good hard working truck. Id like to mainly take strain off my trans and engine to allow them to not work as hard. With the 35s and 373s now if you get on it, its not exactly the fastest. Takes a bit to spool up. Im just wondering if i should go ahead and do 456s to give it some good down low grunt. Whats the best budget locker that i can upgrade my rearend with? And then i guess buy gears? All this gov bomb talk has me concerned the first time i take my rig out its gonna exploded. Maybe between this year and next i can hunt for craigslist deals to do a 14sf swap and looking into a sas. I looked in my glove box and couldnt find any g80 code listed anywhere.
