Seriously, you seem to have quite a collection of stuff. I think the Saturn IB will be fine as long as the molded plastic wraps are still in one piece, the intertank fairings, etc.
A Centuri Saturn IB with 98% original parts, in the original box, would bring you a pretty penny if you decided to sell it. The Estes version of the same kits go for a couple hundred bucks on E-bay when they pop up for sale.
For just one second on one of the other pics, I saw the big black plastic payload section and said, "Holy cow, it can't be a Cineroc, can it?" Guess not... lol.
A lot of the other rockets look in pretty flyable shape - a patched-up fin here and there, maybe a fresh coat of paint, you ought to have some of them back in the air.
If any of them still have the original shock cords, I'd preempively cut those out and install new ones. Rubber cords that have sat in a box for a decade or so are probably shot and stone-cold guaranteed to snap if you try to fly 'em.
