If your main emphasis is on passing the exams as quickly as possible and you don't really care about learning the material per se then just go through a book from Sybex or MS Press or Syngress for a week before your exam, cram basically. That's what I did and it got me my MCSE from start to finish in less than two months. I don't really recommend doing it that way if you actually want to learn from your MCSE experience, but I already knew most of the stuff and I just wanted the credential.
If you really want to learn then you need a lab with at least three computers (or virtual machines though they might cause issues). I recommend three physical machines that you can reformat at whim because you're going to need combinations of servers and clients to test various things and do the various exercises.
