Moved WP installation to new dir can't login

I moved my WP installation to a new directory with a new domain name (actually had the techy at HostMonster.com do it for me) on the same server and now I can’t login to my admin. It still points to the previous directory which is now empty. What do I need to edit to ensure everything points to the new directory.

Side newbie question – My profile shows I’m a WP consultant and I’m clearly not but I can’t see how to change it when I edit my profile (you either check the box or you don’t, and I didn’t).

Thanks for your help!!
