Cresty, Welcome and Merry Christmas! I would suggest you read through some rebuilds here and evaluate your boat carefully. They ALWAYS need more than we think. Meanwhile you need to start getting the floor out, what underneath it won't be in any better shape. Need to check the transom carefully and honestly, never seen a 1961 transom that didn't need replacing.
As far as paint goes, lots of guys use original gel-coat which is the most hardy material to finish a boat. Thats what it was made with. It is harder to get smooth than most paint. I use Dupont Imron, a very tough paint, many people use a marine paint called Awl-Grip.
Welcome to the board, post some pics!
OK, I got down off the porch and ran with the big dogs...kinda sore now...think I'll just lay here in the flowerbed for a while...

I like old stuff that gets out and runs with the new stuff...
