Business object and CMS page mapping

This is our first experience with sitefinity and we are already in crunch to go your valuable documents.

We are developing a project which has Brand and product as business objects.

Each brand will have different CMS content but product will not have CMS content at all.

We are planning to create CMS pages for each brand and a page for product

Our problems are

1:  how we can map brand with CMS pages (look up tables  may be solution, looking for some generic and flexible way if any)

2: For product page URL rewriting or routing can be used, could not find links
