jc,
Great score. They're great drums and you got great sizes.
As a long-time Fibes user, here's my two cents. Part of the Fibes look is the particular wraps they used. You can get real metal laminate from kitchen-counter companies. 5 mins on Google will turn up a dozen of 'em. Not cheap perhaps, but it would be the most authentic re-wrap.
I would not even consider any of the plastic metal wraps - in a couple months they'll be so scratched you'll want to re-wrap them again. I also would not consider painting them--partly because of the work involved, and partly because no Fibes fiberglass drums were painted.
Here's something to consider: leave them natural, with just a clear topcoat. I saw a Fibes kit on eBay years ago that was a NOS NAMM demo, with no wrap at all so the music retailers could see how the drums were made. Leaving it natural would be completely authentic. Those drums sold for a hefty price.
I bought, from the same seller, a Fibes snare with the same provenance. Natural, NAMM demo. Kept it for several years, and recently sold it...it was snapped up by Steve Maxwell for my full BIN price, which wasn't cheap.
Here are a couple pics of it:
