Quick question for the experts:
When I do the MML and BL do I need to replace the rear driveshaft?
Or, the rear driveshaft replacement before the TT?

No

Ok, thanks!

Forgot to ask about the rear upper adjustable control arms. Do I need them for the BL?

You don't, but I have the upper and lower adj controls arms to dial out some of the vibrations with a 5.5" lift!!! I had to add a 1" spacer in my jeep medic because i wanted to hold out for a SYE!!

1) Generally speaking, NO. That said insure you have a full set of lower control arms and if you can afford uppers all the better. If you can only afford one pair of uppers, do the rears first, front later
2) Rear pinion angle: [this is not your u joint angles]. The rear axle can tolerate an upward angle of about 17 degrees + MAX! If you go past, about 10 degrees you need to consider a scheme to get oiling to the pinion bearing or you will burn it out. [Shoot me a PM and I will tell you how to solve that problem inexpensively.]
3) You should not have any issues with the front pinion angle, but do remember that caster takes precedent over pinion angles.
