It seems to be almost open season on .mobi now. I'm thinking of setting up my first mobile-access site now that the rubble of my various (WML) dot-bomb attempts has faded out of view.

Question 1) Since pages to be served are to be XHTML what are safe defaults for MIME-type (text/xhtml?) charset (utf-8?) and file extension (.xhtml?).

Question 2) What are typical prices for the (non-premium/reserved) domains? I've found at least one name that I like that is not yet taken.

Question 3) Do you have to have stuff (eg a functional Web site) up and running and compliant *before* the DNS/domain goes live? (Ignore chicken-and-egg issues here for a moment...)
