I thought I'd post a status update since I've reached what I would consider a milestone.

I've finished theming the product pages and the catalog category list pages. I'm using a module called, Taxonomy Enhancer http://drupal.org/project/taxonomy_enhancer, to create the "teaser" text for the catalog pages. I'm using it to assign a "Basic Description" field to each category term. When you are on a parent term that has children, it will show this "Basic Description" as the "teaser" text on that catalog page. I'm using the term's normal "Description" field to display the extra text on my "Final Design Xi1 model page.pdf" page from above. It works well for what I need it to do.

I've created a theme override for theme_uc_catalog_browse() function that you can see here, http://www.ubercart.org/forum/ideas_and_suggestions/954/tableless_catalog. Thanks Mike for your help on this!

My next goal is to setup the different user roles and figure out how I can integrate the discounts module into this along with a product warranty registration system.
