How to implement Rich snippets on dynamic pages?

[nrv]

I'm working on an e-commerce website, and I want to recommend to the client rich snippets, however only the main menu pages are the ones that have an actual static landing page, the rest are dynamic content pulled from a database.

How can I implement rich snippets in this situation? or is it only applicable to static pages?

Also when I optimized the title tags and meta description tags, the dynamic content is pulling these tags from the main categories, so Seomoz indicates there is a bunch of duplicate meta description tags and title tags. Any tips for this?
