New customer setup

I need to figure out how to correct the “categories” sorting on my website. I also can’t seem to find how to customize the appearance of the webpage. It looks too plain, I expected the categories to show in expanded view or something a user can see other than a listing of categories. Any suggestions? I want the site feedback to be last, NY attorney’s first, then PA attorney category. I can’t find the sort feature when I login as admin?
