How do I edit the products page in MP eCommerce?

I have a Shop the Shirt page with a little text, a gallery of photos and a MarketPress eCommerce shortcode [mp_list_products category="Tee Shirts" list_view="0"]. Page looks OK, but the Products List page displays the same text as HTML. And includes the gallery which I don't want. It don't see where or how to edit the products page. Actually don't even want a separate Products page since there are only 4 of them and are all displayed on the Shop the Shirt page.
Using Atahualpa theme and latest WP and plugins. The same problem using 2012 theme also.
I have a Coming Soon page set up. Log in as "guest", "visitor!" at http://www.guiomargiraldo.com
Can you help?
