Which order to take MCSA exams?

How would you suggest taking the exams? Will doing any of them first help in the studies for the others? I've been through college classes for 290 & 291, but was thinking of doing 270 first because I would be a little ahead on stuff like AD and the networking. How hard is 270 compared to 290 & 291? I've been using XP Pro for about 4 years, but am currently in a semi-programming position, so I don't have hands-on experience supporting XP clients on a network.

70-290
70-291
70-270
And I'd already done Security+, so the 70-270 was the last in the series. I did it that way because I didn't want to have a super-difficult exam as my last, saving me some heartache and worry when I was trying to complete the actual MCSA cert.
