Ditch the MSPress 293 training kit and pick up the Syngress book and the Microsoft Windows Server(TM) 2003 PKI and Certificate Security instead. After you finish 294 and 298, you will be set up nicely for both the Messaging and Security specializations. After you complete the MCSE and any specializations you could move on to the Exchange 2007 exams.
