Caduro,
It's an adventure. Just take it one step at a time. I got my '51 'burb when I was 19. Now I am 58. Lots of bumps, scrapes, repairs and a super amount of fun from then 'till now.
If you still have your truck 40 years from now, this will be the begining chapter. How you deal with it will be the story. Hey, if it's perfect then you won't have any fun with it.
It doesn't need to be perfect right now. What's important is to get it back on the road. You could drill some holes in the cowl and use a puller and a slap hammar to get it in shape enough to put the fender back on. Cut it out and replace it when you have more skill. Or, take it to a body shop and let them do it.
I advise focusing on one problem at a time rather than all of it at once. Decide you are going to straighten the bumper, and only think or work on that. Then move on the the radiator. Then the fender. You get the idea. Don't worry about the other tasks.
