So I was pedaling up a hill and down shifted, eased up on the torque, felt it shift and then went back to pedaling normally. A few rotations later and the bike just stopped. It appears that I have bent either the Derailleur hanger or the actual derailleur or both. I also stripped the derailleur mounting hole and the derailleur bolt as I was removing it trying to do trail repairs. I didn't have a choice in that the hole was already deformed and I wasn't going to carry my bike back to the car. The problem comes that my bike is a 2006 Mongoose Black Diamond Triple, not a Wal-mart bike, and I don't know where to get parts or if they are even available.

I'd suggest taking to a shop and have them look at it.
It may just need a new derailer hangar (removable ones are common on non-walmart bikes)
the bolt that holds the derailer on is usually steel and is usually fine.
Derailer hangars usually run $15-25 (though there are hundreds of different ones, so don't be surprised if they don't have your particular one in stock).

I agree a trip to a shop is needed at this point to identify problem - I have bent hangers twice one was replaced one was bent back for me with a tool made for such tasks

I haven't gone to the shop yet, but am pretty sure it can't be bent back. The derailleur mounting hole became elongated and some of the threads have been stripped. However, I will take it to a shop tomorrow when I am done with class and give you guys an update. Thanks for your help so far.
