It might give you a few ideas on what you can do. A friend just "reconditioned" my jon but we didn't do anything fancy to it. Just paint and a new transom. I did buy new swivle seats that clamp on the the bench style seats, bought a new motor for it and some other stuff.
As far as the holes in the hull...I know that they make a puddy like substance that hardens like steel. You mash the two different compounds together and fill the hole, mold it...and it hardens...like steel. I believe though, you'll have to seal it somehow to make it water proof.
I'm just thinking off the top of my head...hope it works out.
ps...be sure to check out the "Converted jon boats" link on the left side of the page. Some great ideas.
