The home page is a one off page that is not derived from the template like the other pages in the site. The navigation that leads to the home page is not present on the home page since it would be redundant.
In order to create a new content page that uses parts of the home page you would need to modify a copy of your content page template to include the other parts from the home page. Once you have got it in a new template you can create a new SiteAssist layout based on this. When you create a new SiteAssist layout you will be able to choose the template or CSS Sculptor preset that you would like to use for the home page and the content page, you can use the same page for both if you would like. The other way to do this would be to craft a new CSS Sculptor page to have qualities from both of these layouts. Either way will give you a preset or template that you can use to create a new SiteAssist Pro layout with.
When it comes to the left and right justify and of the text settings that are not supported within the interface would need to be adjusted after the fact in Dreamweaver using the css panel.
