1. If you have a remote like a pronto or MX700 you are not limited to 10, but 16. The 10 limit is normally because of the 1-9 and 0 buttons. With custom screens you can get 16 also some remotes use other buttons for 11-16. 1 on, bright, dim, off, is only one command.
2. Correct, if you have more than a half dozen scenes it get confusing anyway.
3. TN Larry did some drawings that are real good see:
