Coming from a guy who blew up a Dana 35 on 31's and it happened on the street being nice to it, do not invest money in it. I would buy a built rear Dana 44 from dynatrac if I could do it again. That's the way to go, big axles, stout R&P, and plenty of locker selections then save up for the front.
Option two is a junkyard or craigslist tj 44 also a good choice but still expect to pay upwards of 1,000. For that price might as well go crate.
Option three is the ford 8.8, which is a stout axle but usually will require being pulled at a junkyard and the lowest ratio available is 4.10 which is not a good ratio for 35's should you step up. The pinion is also slightly offset to one side which I personally have an issue with. It will also most likely need seals and bearings as well.
In the end you need to be realistic. Decide what tire size and build for it accordingly. Axles are a major part of a jeeps build and strength and they are even more important than the lift itself. You need something that won't leave you stranded, remember you can never over build. Build in stages if you have to. Many do and simply do one axle at a time.
Personally I would go with option one or two. Yes it is the most expensive, but you get locker, axle shaft, and gear ratio choices. Dynatrac axles also have really thick axle tube thickness and will not bend until you're around the 37in flavor which it needs trussed at that point. They also yield great clearance, and come with brackets pre welded and everything set up.
Hope that could shed some light, just another few things to consider
