I have pretty much your exact setup. TJ, stock wheelbase, 4.56's and a Tera LCG Pro. I am only on 3" of lift though. I do have a detroit. I love it for wheelin.' I live with it on the street. It isn't horrible, but when I build my rear 60, I'm definitely going with an ARB or other selectable locker.
I have a standard trans as well, and because of this, you will notice it is back there much more often than if you were an auto. It does pop and bang sometimes, but it is pretty rare. first time it happened I thought I broke something, but it was no big deal. Like those before me have said, you will have to change your driving style. Also, if you have a full locker in the front, kiss 4wd away for snow roads. it is IMPOSSIBLE to make the jeep go where you want to go. it will tend to push really bad like Bart was saying earlier.
Detroits are really reliable. Super beefy and won't let you down. That said, I would recommend saving for a little longer to get a selectable locker for the rear. Before I got my rear detroit, i had a trac lock in the rear and a lockright in the front. It did a lot better in the snow than having both locked.
sorry if this was really scatter-brained and confusing for you. If you need clarification, just ask and I'll do my best to better help you.
