I've been playing with Chargeback 2.0 since I need to understand how it works well. Example is I need to understand the relationship between things like Cost Template, Cost Model, Billing Policy, Fixed Cost, Computing Resources, etc.
So here is the link to the first article: http://virtual-red-dot.blogspot.com/2011/12/vcenter-chargeback-20-concept.html
From there you should be able to find the rest.
Hope that helps. If it does, would be good if you start sharing your learning too.
Have a great 2012!
