I don't feel any further Microsoft certs make sense, due to constant platform changes. I am soured on Microsoft certs, but feel Cisco certs build on each other. Also with the Cisco Academy, I received some college credits, so I can kill two birds with one stone.
Especially given your (fairly typical) outlook on Microsoft certs, you are heading in the right track with more emphasis on Cisco. That said, I urge you to visit some job sites online, and check classified ads in trade mags and national newspapers. I don't necessarily mean you should look for a job right now, but you should try to identify 10-20 positions that "might" interest you. Compile some stats on their requirements. If more than half require a BA, it's probably a good next step; if less than half require a degree, you can follow your inclinations in the direction that suits you best.
That said, remember that a degree is for life and Cisco certs have to be renewed every 2 or 3 years, depending on which ones you've got.
