Hey guys I am very new to all of this so be easy on me

I just recently graduated from SUNY Albany with a degree in Information Science and a minor in Criminal Justice. I want to pursue a career in IT and hopefully something to do with security and computer investigations as from research I have done this is where the field is heading.
I am entry level right now without a job and I was wondering what I should start with certification wise. I have been looking and found that A+ certification is pretty standard and needed. My first question is do I need to take this before I take for instance CCENT or CCNA for cisco. And what are some good companies to take classes with/study from for the certifications.
Thank you very much for your help in advance.
