Bondo up any gouges and bad spots prior to glassing will make for a nice smooth finish.
Remove any loose or peeling glass with a rasp, file, rough paper, grinder, etc.
If you can turn the boat upside down, or at least on its side, you can do a much better
job than laying on your back underneath it working upside down. (but is not actually that difficult).
Rust-Oleum (and other paint makers) makes a primer just for fiberglass.

many good DIY videos on the good ole YouTube on glass repairs
