I have been developing a site for a client using ShopperPress and it's not working well: http://www.westbaytrading.net/wordpress/ — I specifically need to find a wordpress theme or plugin that functions this way: home page shows the categories in grid view, click on a category takes you to a subcategory page also in grid view, showing sub-subcategories or products if there are no subcategories. To me it is an intuitive way to navigate a shopping site but I am having a hard time finding this.

My question is can this been done with MT? I'm not a programmer but I can tweak code as long as it's not too complex.
