Pages that are banned in robots.txt or have noindex, nofollow on them are being indexed and are ranking poorly.

How are you determining this? Are you doing site: searches? If so, this has no bearing on anything really. If the pages are showing up for search queries, then it may be another story.

Googlebot is going to fetch everything that has a reference to it. In the instance of stuff blocked via robots.txt protocol, you're going to see a URI only listing when doing site: searches.

Want to keep those pages out of the index? Don't use the robots.txt protocol and drop a robots meta tag on that page. I've been testing this for a couple of years now and it works like a charm.
