M.S. for Information Systems vs. Certifications

I already have a B.A. from Cal. Most colleges here in California don't take applications from those seeking a second undergraduate degree and I am not willing to relocate. An M.S. in C.S. doesn't sound like a reasonable option because even when I complete the prereqs for a B.S. (calc, linear algebra, OOP, C++/Java, etc.), the M.S. program I'd likely be accepted to wouldn't be that great (SFSU, CSUEB). I'd essentially earn the B.S. portion and the M.S. portion would seem to add little benefit to my job prospects. In addition, I have no desire to be in management or an executive down the road.

I hadn't really considered online B.S. degrees from not-for-profit universities, but started looking the other day. Seems I could get a second undergraduate degree from a decent school with a decent program: University of Florida, Arizona State, or Oregon State, although I am leaning toward University of Florida due to their higher national ranking overall and for the department (around 48th for both).

I guess my dilemma, and therefor question, is the following. I have been working on IT certifications: I have A+, just passed the VCP5-DCV; will be finishing Net+ next; subsequently will be finishing Security+, MCSA, Citrix, and CCNA. I just started sending out my resume, so haven't really heard back. I have also been looking at online M.S. programs in I.T. of which I could probably get into without any prereqs from really good schools like Carnegie Mellon or University of Southern California.

I guess my question is, would these I.T. programs even be worth it if I have no desire to be a manager, project manager, or director down the road? Would they be worth the extra cost competitively, or are the certificates enough once I find a place to get my foot in the door and gain experience?

In all honesty, I have been doing a ton of VBA and SQL programming at my job, and have become more interested in C.S. However, the M.S. in IT route is a more immediate solution, but whose value may not be worth it in relation to certifications.

I am pursuing a graduate degree in the humanities at present, given that is my passion. However, the competition for positions in a field where many departments don't have the money, or need, to expand and tenured professors who never retire, makes for an uncertain future. I figure whether I pursue the B.S. in CS or M.S. in IT, I can do that during the day, and still pursue teaching at a university at night without having to teach six or more class a semester all over the Bay Area. So that is why I have no desire to be in management: I don't think I'd have the extra time to teach.

Thanks in advance for the advice!
