Scribe Modification--Adding Pages, etc.

The tutorial isn't answering all my questions.
Can I delete some of the social media icons/links on the header or footer?
There are some pages linked in the navigation menu in the header. Can I use them and modify them like the home page, or do I need to create new pages. I can't find the pages linked to when I click on posts/pages in the Upfront panel section.
Thanks.
