There are alot of good calculators and charts for use on this and they are all pretty much the same with final results. Pirate 4X4 has alot of reference on this subject. Here is a chart that I keep in my garage and has worked extremely well in all the setups that I applied in too.
1994 Chevy C1500 RCSB 05' DBW 5.3 Conversion CompleteMy build
Coming soon ....... Full Repaint, 214/220 Cam, Yukon Posi with 3.73's, remove body lift
I'd go cognito as well. They are well made. I have a 02 Yukon XL with 4.10's on 33's and it goes ok. I don't want any more rpm since it is mostly a family highway vehicle. So I put a YANK 2600 in it to help out with the off the line. My last truck (05 ECSB 2wd) had 35's and 4.56's and it moved well. If I was doing more commuting I would have gone 4.30. My buddy's truck (check long travel truck in for sale section) has 4.88's and 37's and it was almost a necessity. Partly cause it is a 4.8L with a 224 cam and 4000 stall, there is a lot of weight to get moving with not much torque.
So IMO if it's going to see a bit of highway time, go 4.56
If you want the power or are towing go 4.88

Sorry but I'm going to be that a**hole that suggests you do a solid axle swap. I think it's worth it to save up the money and parts and build a proper straight axle setup. You can buy link kits to help eliminate guess work and you'll have a truck that every guy with a "lift kit" will drool over. Some guys argue that you can't get the ride quality out of a solid axle that you can with IFS but those guys haven't ever ridden in a properly built coilover shock setup. I rode in my friends truck ('96 SAS'd ECSB) and he has coilovers all around and it felt like riding in a big offroad cadillac. Now, granted, he had the nitrogen on the shocks at a lower than normal psi but that's easily a quick fix. He took me down this beat up pothole laden road and I didn't even spill a drop of beer haha. I can help you with the selection of parts considering I've spent the last 3 years researching. Trust me, it's worth it in the long run
