Getting to grips with Project 2007

Microsoft Office Project Server 2007 - to be formal about it - has been on the price list and RTM (Released To Manufacturing) for nearly three months now. And it's still hard to find definitive manuals or books about how to configure and use many of the new features. There have been a number of white papers and promotional documents released. These typically address technical installation (up to a point) and quite a lot on the server side architecture.
But best practices for how to use the new time sheet feature, reporting the new budget category costs, using the new resource plan feature and so on are elusive.
Most information is being spread through blogs, such as Microsoft Office 2007 Project Blog and discussion groups.
Microsoft does offer courses which are loosely described as 200-300 level. Information on these can be found at the 'EPM University'. The curricula for the two courses offered at the moment do not look as though they answer the Best Practice questions. For now the best source is still individual experience!
