Need info on replacing a bumper

backed into an invisible pole today

So my right tail light is busted (I’ll order and replace that myself) and the right bumper cap fell off. The cap is fine and intact and the clips are good but the black plastic piece underneath is busted. I’ve got it gorilla glued back on for now but I’m going to replace that as well. However, I have no idea what piece that is and how deep I need to replace stuff (as in, this part connects to another part and you need that one too). Help is greatly appreciated on that.

Also, my right side of my bed is scratched and dented to hell. I’m going to try to pull out the big ass dent using some DIY tricks but I’m definitely going to have to paint it.

 

I think this is what I’m talking about.
