If you are talking about your individual product node display, then you'll need to create a template file to achieve what you want to do. If your node type is product, then you would duplicate your theme's node.tpl.php and rename it to node-product.tpl.php (or if you have a product class assigned to a cheese content type, then it would be node-cheese.tpl.php). You'll also need to use the devel module to look at the array structure in order to see which php print statements to sprinkle throughout your template file's markup.

I can't get really get more specific than that, but there are plenty of introductory theming videos out there from past camps and cons. The Lullabot theming videos are also stellar.
