I just wanted to post this quick reply while I am thinking about it and before I read the rest of the intervening posts...

This deserves a thread of its own!

Well as I said if the noindex page has PageRank and it is not displayed in the toolbar, the toolbar values are fake. If that is they case, the toolbar sucks more than my imagination could perceive since I am working as an SEO professional. |
Toolbar pagerank IS NOT internal pagerank. These are different values, scaled and calculated differently. They are based on the same information as internal pagerank, but they are very different values.
Internal pagerank is a value between 0 and 1, which is a ratio indicating the odds that a random surfer starting at a random page in the index and clicking a series of randomly selected links (3, if I recall correctly) will end up on the specified page.
Toolbar pagerank is a weighted scale of the relative link strength (number of inbound links weighted recursively by the number of inbound links to the linking pages) of the specified page, indicated on a scale from 1 to 10, weighted so that 1-2 contains exponentially more pages than 9-10.

To remember those pages do those pages need to have PageRank?

Technically, no. However, since a page can be marked as NOINDEX, FOLLOW and pass pagerank (and therefore must accumulate pagerank) it does not seem logical to me that a page marked as NOINDEX, NOFOLLOW would not accumulate pagerank simply because it has no followable links. Google's algorithm already has a mechanism to distribute the accumulated pagerank so I see no reason it would not be accumulated just because the links aren't followed.
