and I need some advice.

I'm 33 years old, have a BS in General Science, and am taking classes towards a Masters in Information Systems. I'm looking to get an entry level IT job to start building my resume. The problem is this: I have almost zero certs (just A+) and zero experience (my background is mostly in business to business sales). I want to go towards the networking side of things so my questions are:
1) Does a MS in Information Systems help?
2) What certs should I be working on next? Network+ ?
3) Any advice for getting an entry level job? (I need one sooner than later, lol)
Thanks in advance for all of your help!!!
