What would be a good product to fix my bumper with.?

The push-in fasteners popped loose. They might still be there and you can just press them back together like snaps. If you lost them, get replacements from the dealer. They come in different sizes, depending on what part of the body they are applied to. They aren't cheap though- a few dollars each.

A new bumper.

Buy new plastic clips that hold it in place. You will also find that there is at least one bolt holding it near the wheel. These bumpers are basically held in place with plastic push in clips. You can buy them at any auto parts store.
