Honestly, if you're looking to learn them, there are plenty of resources out there. If you want the cert, I would suggest a certification specific class, as the cert tests contain many, many things you will never ever do in real life.

You could get info here http://www.microsoft.com/exchange/en-us/learning-resources.aspx

or there are a few books.

  If you just want working knowledge, The issue is that its fairly common knowledge, at this point. You may want to look into a specialization around one of those programs? Maybe DR, cloud infrastructure? Administration is too commonplace to make a dent in your future, IMHO.
