Using robots.txt, a blocked page can still be indexed by Google (URL only, or with data from trusted 3rd party sources) and receive PR if linked to by other pages. But its PR won't be passed to other pages.

If you use the noindex metatag then that will prevent the page from appearing in the index at all, but the page will still be crawled and will receive PR from backlinks, which it will pass on to the pages it links to.

However, you shouldn't worry about "clogging" SERPs. If people are linking to those pages, then clearly they're of some value to web users, therefore they should be indexed and appear in search results.
