Theming

This is how I did it:

I created page-front.tpl.php and page.tpl.php
The page.tpl.php is the simplified page for the rest of content without header, primary menu, etc. This is the page that are being called to be inserted into this designated iframe. is this the way to it? I still have "admin_menu" top bar on both page though.

problem, If I refresh the frontpage, the iframe become small. Clear cache, reload then OK (auto expand height).
