So I finally got a lock ring tool and chain whip this past week, so yesterday I got after removing the cassette and the rest of the drivetrain from my KHS bike.

So anyway, after removing the cassette, I noticed a slight bend in a couple of the spokes near the hub, and a few rust spots on the free hub itself. Should I be concerned about it? I cleaned off the rust as best I could, and everything was dry when I put it back together.
Wish I had taken pics before I started, but here is the end result:
