2.0 does NOT use a "theme". It uses the standard Joomla "View".
The view folders are located
Doing a Joomla Template Override is easy.
Open the view folder you want to change, THEN, the tmpl folder.
COPY the "default.php"
THEN< follow the steps below.
In your JOOMLA template folder. You create a folder called "html" then a folder called "com_virtuemart" in it.
Then for each view you want to override. Create a folder for it.
Then place your modified "default.php" an that views folder.
So , to override the product details page. You create YOUR_TEMPLATE/html/com_virtuemart/productdetails/default.php
Doing a Joomla Template override guarantees the view will use your modified default.php
FOR changing the css. What you do is copy the virtuemart css located in
THEN, add that to your joomla template css file. (or call it seperately, AFTER you put a copy in your Joomla template foler)
THEN, go to vmart configuration, and turn off virtuemart css
