I had relatively good success bending my bent bumper back into fairly good
shape.  Original replacements are listed at either parts.com or carparts.com
(one of them also lists just the rubber strip).  Fastgerman.com and others
sell a heavy duty tube bumper with a 2" receiver.  I have no experience with
these bumpers, but would be interested if I ever get around to replacing
mine (I would love a trailer hitch).

Good luck.
