I've recently (6 months ago) got my dream guitar, a 330. Always wanted one and finally got it. Tonight I've noticed a black mark on the back I don't remember seeing before, although it's possible it was always there. It's on the back on the top cutaway near the strap button. Next to it is what appears to be a really fine finish crack. I've included a photo below, although it's really hard to see.

You can almost see the finish mark(crack?) at the top where the flash hit the finish and it follows the curve of the point. Is this something I should be worried about? Should I assume the black mark is part of the grain and always there and i'm only just noticing?
I do have one small similar finish crack on the point of the bottom cutaway and the finish feels somewhat bumpy along some of the edges, possibly orange peel? Is this just the finish settling down and shrinking?
Sorry for all the questions, I just want to be sure my new guitar isn't in danger of any damage. Thanks for any replies.
