Oh, I forgot to comment about the head badge. I suggest removing it. You'll need to knock off the backs of the rivets from inside the head tube. A screwdriver will usually do the trick with a few taps. The head badge is probably very thin, so remove it carefully. If you have to use much force, it means part of the rivet is still there. After you've painted and let it dry for several days, you can reattach the head badge using clear silicone caulking. The holes will guide you as to placement, but there's no need to re-rivet or screw it on.
