I know they are currently building out the Marketo University: http://learnadmin.marketo.com/LearnerPage.aspx
and that Analytics and Reporting are reviewed in Marketo Foundations. I'm not sure if they still have the on demand version of the foundations course but they have classroom and live virtual courses (paid). This gives you a good basic knowledge of all parts of Marketo.
There is also quite of bit of documentation in the Marketo Docs on reporting including info on Revenue Cycle Analytics: Reporting - Marketo Docs - Product Docs
Hope this helps!
