Yes, they can regrow their appendages - there has, in fact, been a lot of
research on this, because regeneration in a vertebrate is a trick we'd
dearly love to adapt for our own species.

Hmm. I'm not so sure there really is anything you can do for him, and
honestly I doubt that if it's been broken for a long time that he's still
in pain. Were it my newt, I'd probably talk to the place I bought him and
say "I'll keep him and see if he makes it, but if he dies as a result of
this pre-purchase wound I'll expect reimbursement" - and then let nature
run its course.
