a BS/BA is some form of IT is always a good thing, but if you've got great experience you can get by without it. It depends on what is needed, being a tech firm we have technology we are maintaining, and something we a pushing towards (new) always, so it varies..
I'm mostly responsible the security work, so you need to understand those concepts to be on my team, firewalls, networking basics, exploits, ALOT of policy/paperwork/compliance.. a good networking and server background is perfect for entry into the security field. You can learn fast, but it takes time to be very good. The other 2 groups I have responsibilities with are infrastructure (Windows, Servers, Virtulization, Cloud Computing etc...) and Managed Services (People pay us to do or provide for them).
I could talk about this to no end... but I won't.. if you ever need anything or have questions let me know.. If you work for an IT company in the area, chances are I know someone who works there too.
