That's the sort of thing you would use a palm router for... fiberglass doesnt react well to a hammer and chisel.
Ordinary wood screws that came with the deadbolt will hold in the fiberglass if you drill a small diameter pilot hole and dont spin (strip) the screw. In other words, tighten them by hand.
As for the missing chunk of door, about all you can do is Bondo it. Use masking tape to confine you Bondo to the repair only so as to keep the rest of the door clean. Then sand and fill again until its the shape you want. Then paint it.
