I probably sound like a broken record, but...do you want to get certifications in 7+ year old technology, or in what is most current?
FWIW, the MCITP Server Administrator is essentially equivalent to the MCSA, and the MCITP Enterprise Administrator is essentially equivalent to the MCSE.
That said, there are a number of companies (at least in the US) that are adopting Win7/Server 2008. Knowing the most current client/server technologies is always the best recommendation.
