Get to know the Sure Step role-based learning roadmaps: https://mbs.microsoft.com/partnersource/partneressentials/serviceplans/surestep/
Work through the Introduction to Sure Step eLearning ( http://go.microsoft.com/fwlink/?LinkID=182558&clcid=0x409 ) and Using Sure Step on-demand courses ( http://go.microsoft.com/fwlink/?LinkID=182559&clcid=0x409 ). You need to be an MS Dynamics Partner with active plan to see these.
If you can download the 80199 or 80235 training courses from PartnerSource and work through those, it would be really helpful.
