All those issues are very minor cosmetic things. You were expecting a board with a few dings/scratches and that looks like what you got.
Edges get surface rust when exposed to water or even high humidity. Rain isn't going to hurt a board.
The base goes white when its dried out, all new boards need wax anyway. The factory wax was applied months ago.
binding marks could happen if it was a store display.
Again, it's all cosmetic, and you knew it wasn't pristine, so go ride it and stop worrying.
