I agree with most points, perhaps with the exception of point 6. I don't think it is essential for the employer to provide accommodation or be the signatory on the lease because some teachers prefer to find their own accommodation. So long as both parties are clear about the arrangement then it just becomes a matter of personal choice. I dare say that a good contract would give you the choice of either staying in rent free school accommodation or living outside of school accommodation at which point a contribution towards rent is usually made.

The general problem in china at least is not that the conditions you stated aren't written within an employment contract or promised to teachers before they arrive because most of the time they are. It's the fact that those contracts and promises are often broken. The basic idea of contract law in china is not on a par with that of the west. It is usually that gap in expectations that causes the most problems between foreign employees and local employers rather than any single condition.
