Help with setting up directory

Looks like the detailed installation instructions page is being redirected back to the description page.

If I add custom fields through custom press, how do I get them to display on the profile page? Do I need to change the css? How do I determine whether they would also appear on the preview view?

is there a way to have a list of categories and a list of those businesses that are in those categories appear on the main page in place of or in addition to the search box?

thanks!
