I don't see why you shouldn't just use one CSS file for the entire site, and use comments in the CSS for each section.
I believe that there are 5,000 lines in the main.css file because it covers all the different templates that come free with X-Cart - is that correct? If it is, it seems like the wrong way to do it - a better way would be to have a separate CSS file for each template, and only call the CSS file which fits each template.
