Marketpress Lite v Full differences

I recently upgraded from Marketpress Lite to the full version, but noticed some differences that I didn't expect, and want to "revert".

1. Product listing on category page used to have CSS attributes for the category. Before, I could set CSS for #mp_product_list .category-my-category div.mp_product_meta -- however after the upgrade, that doesn't seem to be possible. This greatly reduces my control via CSS.

2. Now, every product shows a "no image" thumbnail, however before it just didn't load an image. I just don't want any image to show up.

Any clue how to "fix" both of these issues to how they worked under Marketpress Lite?
