Just a quick tip from me. Ever since I started working with the new Virtuemart 1.1 themes,  I've always found it hard to find my way around which templates apply to which pages.

Therefore, I took the default template and made HTML comments in all of the theme-files. That means, that if you're ever in doubt on which template you have to edit, you can just view the source and a HTML comment will tell you.

You can download my commented template at this link

The folder is called blank, but you can basically rename it to whatever you want. Just make sure to rename it in the theme.xml file also! Place it in the "Themes" folder in com_virtuemart and you're ready to go :-)
