There are a number of ways to repair those two areas, but because the top picture is in the white gel-coat I would buy a small can of white gel coat and ue it for both repairs. There are many shades of white but if you have the piece that came out you can match it close enough. I would grind the opening around the hole to remove some resin,wipe with acetone mix the gel coat and allow it to partially polymerize to where it just starts to thicken so it does not run then apply several coats to the hole. Cabasil or small chopped fibers should be mixed with the first two layers. Last layer should be pure gell coat and applied thin. Once sanded with 400-600 grit sand paper and buffed with a polishing compound you should not have to paint. The bottom crack is not a stress crack it looks like something hit the area so I would not worry about the crack growing but would sand and apply one layer of woven FG cloth wetted out with the same gel-coat to the backside if you can and grind a small V in the front side of the crack. After wiping with acetone fill the V with gel coat as in the first repair. The bottom would have to be painted to match the exiting color. Good luck.
