One place to start is the DNS Server Operations Guide and the DNS Server Help on Microsoft Technet. The various DNS Manager functions are documented against the tasks that they form a part of.
Once you have done this the best learning resource I can suggest is spinning up a test server and having a play with it and it's features - from there you will be able to raise more specific queries that you need answered.

I would start by looking at the Microsoft Technet Site, it will outline the changes to the DNS Service in Windows Server 2008 R2.
