Xbox 360 version

Is there a place with the drop rates for keys and caches for the torment levels and anything else helpful.
So much info out there that does not pertain to my situation.

Correct because the 360 version was not updated after patch 2.0.6 (I think). You’re playing a very old version of the game there. The general rule of thumb here is to do the highest difficulty that you can do efficiently to farm to maximize your chances.
