FYI: jessicabissell--I believe you can 'search' vanity url on FB and get a page that explains how to change your URL. You will need a minimum of 25 'friends' before you are eligble. Just a word of caution...as I have learned the HARD way. You might want to use a different email address for your Fan Page which helps separate your personal friends/family from biz fans...unless you want everyone involved.
