I'm sure that the Outkast kit is fine, but I've got enough experience with Backwoods Armor to have confidence in recommending them.
Ask 3 people and you'll get 4 different answers.......but you asked, so here's my opinion on the lift and axles. Any lift at all will decrease reliability of the CV joints, but I feel that lifts exceeding 2" are much worse on stock CV's, so I typically discourage 3"+ lifts when they can be avoided. Unless you're a deep mudder guy that wants/needs every inch of ground clearance you can get, the best method is to use as little lift possible to clear the size tires you're wanting to run. I'm pretty sure that you can clear 28's with only the forward arms, but you're gonna also need a lift to clear the 29's. Keep in mind that all tire sizes don't run true to their advertised size.......many can be larger or smaller.
As long as you don't drive it hard and be cautious about turning the wheels hard (especially when in AWD and/or in reverse), the stock CV's will hold up decently. With that being said, eventually you probably will break one....and when you do, I'd upgrade to something a little beefier. I ran stock CV's with 28's for quite a while in my Ranger before I had to upgrade to Gorilla axles. I have only broken 1 CV on my RZR since adding 30's, but that was my wife's driving error and not really related to tire size and axle angle.
