New to Microsoft, looking for study material and advice.

Just received my CCNA and now I want to move onto Microsoft!
What is the best path to follow? Should I work on 2008 or jump right into 2012? I love CBTNuggets so I'll probably get those but I'm looking for reading material as well. What do you guys use?

I don't have any requirements for my job but we do use 2008 R2. With my current position I don't get to play with the servers all that much and I don't see anytime in the near future.
I think I'm just going for the 2012 version and learn as much powershell as I can on the way.
