I very much hope he does not give you negative feedback, but I think you are right to do the edits, even if it goes against the grain, and then to close the contract.
If your feedback is less than stellar, then I would definitely say something, but keep your criticism short and professional.
Thumbs up to what Nichola said. Be careful and tread lightly, even though it may grate on your nerves. You don't have much feedback under your belt and this badly behaved client could really tank your as-of-yet-in-development JSS. Had you many jobs recorded with stellar feedback my advice would be a bit different, but in this case be professional, probably moreso than you feel like being.
