Hi Rowley4,
The truth is that you have to do what makes you happy. If your goal is to stay in IT but not code, an MBA probably won't help you all that much, whereas an MIS degree probably could help.
The key is not about how educated you are so much as how hungry you are to be successful and to learn new things getting there. I've had many employees and seen many people in the IT industry who did not have advanced degrees and who excelled far beyond many that did have advanced degrees. I've even had employees and friend that had no college degrees at all and still found ways to be successful. It's really about you and your personality type.
That being said, to my knowledge an advanced degree has never hurt anyone. It always shows that you went that extra mile to learn.
Another option is to get a job with a company that will help pay for your advanced education. You can spend a year or two learning about what you do or don't like, which might make your decision easier.
I hope this helps.
My Best,
Frank
