70-270

Hello,

I am studying to take the 70-270 Exam.  I am planning to buy the MCSA/MCSE Self-Paced Training Kit (exam 70-270): Installing, Configuring, and administering windows xp professional, SE.  I noticed that this book was published nearly 4 years ago (2005), and I was wondering if it will cover all information required to successfully complete the exam in 2008. 

Will this book be sufficient, or do I need additional study material.  If so, what do you recommend. 

Thanks in advance.
