If the skin is starting to come loose, you can try to take hold of it and let the snake move naturally, that might help it come up.
As to the eye caps, everything I've read here says that they might come off after a few days if the snake doesn't get them off himself today. There's a chance however, that if you can get your fingers on that head skin and very slowly try to work it off, the eyecaps will come off with it. That's what happened with me.
