Help with Rear end gear ratio

okay guys, I have everything from 3.91's to 4.88's. I already have the 30" tires so I don't want to have to buy another set. I got these for 50.00 and they only have 10 runs on them. So I really need to come to some sort of resolution here. In a perfect world I would like to only have to buy one set of gears. I was planning on running a 5500 stall, and a trans brake. Haven't decided if I am going to use Super Stock Springs or CalTracks. I like the dollar figure on the Springs vs CalTracks.
