+1 on what londrum says and plus my $0.02 :)
A couple of months ago, we tried noindexing and blocking pages via robots.txt. Unfortunately, Google was still listing these pages in their SERPs but without a snippet below the title.
The only way to get them out of the index was via webmaster tools and even now, there are errors about these pages being blocked by robots.txt *sigh*
