Last year I did address the floor on my '77 C10. There was of course rust to deal with. But it was only topside, the underneath was fine. So i wire wheeled it, neutralized the rust with POR-15 Metal Prep, then paint over with POR-15. Then I put down some Dynamat, and on top of that some closed cell foam.
