Just bought my first brand new board.. With dings? :\ (pics)

Picked up a fiberglass 9'2" for $300. I'm still a n00b surfer so I didn't really inspect it all that crazily because I didn't know what to look for anyway. Looked good after about 5 mins of looking over it so I pulled the trigger on it. But now that I'm home with it and really inspecting it, I'm noticing a few very small dings (one admittedly my fault from bumping it on something) and some scratches on the rail... Do I need to get the dings/scratches repaired? Also a couple very small air bubbles in the foam. I feel like these are normal things for a board to have, but I'm starting to get a little paranoid that I got ripped off.... Take a look at the pics and please let me know what you guys think..
