Hi, to change the name and the URL of your wiki, just head over to Special:Contact/wiki-name-change and request it.

Admins could protect pages against either non-autoconfirmed user or non-admins--the excessive use of these are not advised due to nature of wiki. So, no, you can't make pages editable only to the OP; unless they are admins.
