Agree with the above comments - the only reason why you would want a certification is because you want to be in a technical role and you are seeing specific mentions of it in job postings. I have held both of the certifications you mention (though one is on a version so old as to be irrelevant, and the other is expired). Both would look good if you were applying for an entry-to-mid level position in technical support or systems administration. Neither will get you into senior or architect roles without relevant experience or knowing someone.

As I'm sure you know, as a manager a completely different set of skills apply. IT has a bad habit of promoting managers from within its own ranks, which may work in your favor. Skip the certifications and just read up on new trends and technologies - breadth of knowledge will be better than depth. Your excitement about technology will also be a great asset.

Good luck!
