If there aren't any, don't let the body shop you go to convince you it needs to be replaced if you don't find anything structurally wrong with it. If there are dents, then can be removed easily. As for the windshield fluid container, they're relatively cheap.

Total bumper respray: approx. $450, shouldn't need to pay much more.
Windshield container: $48

There might be other parts broken behind the bumper, like the bottom heat shield or foam barriers.
