First Sailboat: Laser with major hull damage. Repair advice needed.

I picked up this boat with a trailer for $400 the other day, and am really interested in getting back into sailing. I have never done fiberglass repair, and am looking for some advice about where to start with this pretty gnarly hole.

About hand-sized. Foam is on the inside below the fiberglass and is not mushy

there are a few other smaller cracks (see aft hull near rudder), and some I can't tell if they are just in the gelcoat or actually have impacted the glass (a few smaller spiderweb-y cracks on the bottom of the boat near the daggerboard hole), but regardless I would really want to get this boat in sailable shape for the summer.

Note the crack on the deck and rubbing from the tiller. And the massive hole, note that too.

The previous owner had the hole covered in duct tape and just prayed that he didn't flip starboard I guess...
