Does Google places less importance on URL's with session ids. What negative implications does it has ?

You should avoid duplicate page titles (meta titles) on your website because the more duplicate content and duplicate page titles (meta titles) you have on your website, the worse those pages will rank in the search engine's pagerank.

I'm not sure I understand the question
Do you mean overall or are you talking about how those URLs might be hard to get indexed?
