One other formatting issue:
I have a php file handle formatting for my store front, and xcart for the product page. They both use the same css values. For some reason, the contents of the product page shift slightly to the right when transitioning from the store directory. Go to the link below, then click any of the shirt icons, and notice how the contents shift roughly 3 pixels to the right.

Any idea why?
