Aww, poor baby. Far as I can tell you're doing well. There are only two things I'm a little concerned about, maybe someone more knowledgeable here can tell me if these are a problem: 1. rinsing him in water from the shower/faucet that isn't dechlorinated. 2. Rubbing his back a little much maybe. Oils and salts in human skin aren't really good for frogs, maybe having an imperfect shed would be better than being exposed to them quite so much.
