Advice with fixing dents

Hey guys,
I was in the woods while it was raining and my taco slipped and hit 2 trees. It left a big dent on my rear right door and and trashed my rear right fender. Any advice on fixing this? Can I replace the rear fender or do I have to replace the bed and door?

 

I would probably just rock the dents unless they are really bad. And get sliders.

 

The metal bed side is replaceable, but expensive. The flare clips always break trying to remove those as well. And if you remove the inner panel on the door you can probably push some of it out, the paint will probably crack so it will need repainted or it'll rust. Same as the bed.
