I too would say keep the 2.9L if it's running well.
Mine has probably in the neighborhood of 340K miles on it (a guesstimate since I had the speedometer disconnected for a few years, and also tallying all the driving in low range I do that doesn't accrue the miles on the ODO as quickly as street driving does). I bought it with 140K back in 2004. It's one & only issue is a bit of light oil seepage around the valve cover gaskets (mostly noticeable only if it's been parked for a week or longer). It doesn't burn any oil, still handily passes state emissions testing too.
Yeah it's certainly no powerhouse, but with the right gears for your tires, it's adequate enough to maintain speed on most highway grades with a downshift to 4th (I run 35" tires with 5.13:1 gears... 4.88:1 would be right about the same with 33" tires).
I would suggest a crawl box (a.k.a. 'dual t-case' or 'doubler') rather than convert to an automatic trans. A crawl box should solve the stalling issue you mention, and should make for more graceful decents down the other side of huge rocks or steep downhills since you won't need to stand on the brake as much as you would with an automatic. As said, the A4LD auto has it's issues, it's tendency to run hot probably the most significant (external coolers do help a lot, but occasionally it still seems like you can't have enough coolers sometimes).
Also, I would suggest keep your lift short and trim the fenders for tire clearance if needed (more than 6" total lift is asking for a rollover). My suggestion would be 3-4 inches in the suspension, 1-2 inch bodylift. More than 4" in the suspension, and your steering linkage angle starts becoming unmanageable.
Hope that helps.
That's a nice lookin' truck too, BTW.
