Edit Top Navigation in Business Theme

Hi, I have the Business Theme and it does not allow custom menus in my WordPress Dashboard under Appearance>Menus. But there are pages I don’t want in the top navigation area, pages like Protected Content and Sample Page, etc. How can I remove those from navigation?

Also, I can’t find a way to order my pages, i.e., set some up to show or not show in navigation, set some up as sub pages of other pages, etc. Where do I do this?
