Upgrading to MCSE 2003 two years after taking 70-292

Hi all,

I am a MCSE 2000 and I have taken 70-292 back in August 2004. After being
transferred to network department almost 1.5 years ago, I have not been
taking a single Microsoft exam and I am thinking of resuming upgrading to
MCSE 2003. I realized that a lot has changed since the release of Windows
2003 Service Pack 1, R2 and WSUS.

Has Microsoft exams been updated to SP1 or perhaps R2? What about SUS vs
WSUS?

I have never use MS Press books. Are they good? Thanks.
