Just to clarify, I don’t want to claim that pyviz.org is the most up to date; it’s probably the opposite. pyviz.org is where we show how all the various projects fit together to solve problems, and as such the most bleeding-edge features are likely to be better documented in each individual project, whereas how to use them together is documented at pyviz.org. We’ll be updating all of the websites over the next few months, but yes, it’s a continual struggle to keep up with the rate at which each of these projects are progressing!

We’ve recently set up http://pyviz.org to help demonstrate how all these projects fit together. I’d recommend going through the tutorial at that site, which sets up an environment including all of those packages along with examples of how to use each of the projects separately and together. Stay tuned to that site; we’ll be trying to put a lot more useful stuff there over the next few months!
