If you want to make a new page for the site you should do so by modifying the SiteAssist site. You can manually create a page that you don't want to link to by creating a new page from template and choosing the SiteAssist template.
You can also use Menu Writer to apply a new menu to your CSS Sculptor page. Other than this you would just cut and paste the menu code from the template file into your new page. There are the css references, the js, and the include for the menu itself.
