You definitely don't want to use the nofollow attribute along with noindex, as nofollow would stop natural PageRank circulation on your site.
I'm not a big fan of noindexing. I think of it as a bandaid approach, but it's not a long term fix for thin content (more appropriately for Panda, "shallow" content). You've got to do the hard work of creating new content.
For certain kinds of duplicate pages, if you can't fix the duplication problem structurally or on the server, the rel="canonical" tag is a better approach than noindexing.
