There's a number of great fiberglass boat structural restores going on here right now. I'd suggest just clicking around some of the restore threads. If you're more of a video type guy check out Friscoboater's youtube channel https://www.youtube.com/watch?v=kopF4muvF0c&list=PL02C318B574CD948D
How are the stringers? usually by the time the deck goes the stringers and transom are pretty rotted as well.
