Want to get into Computer Forensics

I am a criminal justice major, getting a certificate in IA. I want to get into computer forensics after taking a couple courses on cyber crime and computer crime. What do you all suggest I do in order to bolster my resume? I am working on my A+ and Network+ as something to fall back on, should I also look into Security+ after I get Network+, is there something better out there for computer forensics. Any help or suggestions, as always it is appreciated.
