The bumper guards and scratches on the bumper make me suspect that it was a service truck for a shop, or a service station back when they actually provided service. The rubber covers probably went from top to bottom to keep from scratching the bumper on the car being pushed. We had a section of tire on ours back in the fifties.
As for what to do to it first, the old saying is make it go, make it stop, make it legal.
After that you can mostly pick and choose what you want to do next as far as appearance and comfort items. You have a BBW and the dash hasn't been mutilated in the radio location so that's a good thing.
