With all of those parameters, it's doubtful that your site is being crawled efficiently.  In other words, the Googlebot gives up before it has a chance to crawl all of your pages. You should be able to configure URL parameters in Google Webmaster Tools to let Google know how to handle each parameter. This presentation breaks it down.

Hi,

Paramaya raises a good point, you should use Google Webmaster Tools to set certain URL parameters to be crawled, ignored, ect. However, I wouldn't rush to say you don't want Google crawling those pages, since they may add value in some way.

I think you should add canonical tags to the pages with URL parameters that point back to your site's main page. This way, Google knows and crawls the URLs with parameters and attributes value and relevancy to the page being pointed to through the canonical tag.

I help run a top 50k ecommerce website, we use canonical tags and GWT to handle such issues.
