I guess I am curious about why you don't take over from the yard and finish it yourself. The fibreglass looks fine in the pic. The remaining wet spots need to be dealt with though. Don't let them seal and paint your hull while it is wet or you may be setting yourself up for serious problems.
Dry them out. If there is any soft stuff in there try to get it out without destroying or cutting the fibreglass roving strands. Then mix up a bit of home made chopped strand filler (put some fibreglass into a blender full of water and chop it up a bit. Pour it out through a fine sieve ((nylon stocking works well)), let it dry and mix it into your epoxy). Work this in to the holes you dug getting the wet stuff out. Don't put too much in - you primary goal is to seal it. Make sure that your epoxy does not form a bump that protrudes at all. If it does, then you will find it very dificult to get the hull smooth, as the epoxy sands less readily than the gel coat, hence it is very easy to gouge the gel-coat while you are trying to get the epoxy smooth. Particularly on a curved surface.
When the fill has dried, then apply a thin barrier coat of epoxy over the exposed fibreglass. S1 sealer is good for this. If you use S1 put on three thin coats, but make sure that the S1 is still a little lowewr than the undamaged portion of the hull.
When the S1 has almost set up (maybe 16 to 24 hours in warm weather - it should still be ever-so-slightly soft but not tacky), run a coarse piece of sandpaper over the surface once - no more - just enough to abrade it - not remove it. Now use a very slightly thickened polyester resin or unthickened gel coat to build up the remaining 1/16 depression and fair the hull.
If you let the yard finish it, make sure they deal with the wet stuff and ensure your hull dries out before you seal it up again.
The other "crack" is not an uncommon thing. Has probably been there since the boat was built. If you are worried about it, then try running your fingernail or screwdriver along it to see if there are any soft areas or voids. If you find any, sell the boat fast
