I did 290 first, and that helped with 270. I could have done it the other way around just as easily. Keep in mind that you are also able to apply the Vista configuration exam, 70-620, to the MCSE as well as the 2008 Server/Enterprise Administrator MCITP. You may want to consider taking that instead of 70-270.
