You cant .... The HTML Catalog feature is ONLY for Products and Categories... Anything else you click on will take you back to the PHP side of the store. You would have to implement one of the SEO Mods you find here in the forum in order to make everything HTML. Except for when you go to the shopping cart it will go back to the PHP side. But if you start to click on products again your back to HTML. Basically re-writing PHP to HTML.
You can navigate around my site and see how one is implemented.
