Help with setup of product listings

Hey PC,

Ok, I got Market Press installed and somewhat configured. Please take a look at my menu, it has a menu choice of Video Store under the services choice(Sub-menu). On the Products page I would like to have all the categories, Now it has the one dummy product that I set up? I'm selling Downloadable Video clips that will be categorized in a number of categories and sub-categories. Do I need to set up a page for each category? I would Love to have the products page set up similar to the Portfolio page.

Once I get this set up I think I will want to make some changes to the buttons and messages in the store Market Press to reflect more of my theme's design.
