Where should I start? Should I post somewhere else?

I literally know nothing really about networking but am so sick of my job I would love to start learning and get my certifications I need in this great field. I am close to a 2 year degree in Computer Science and am a freelance web designer to give you part of my background, although my job title is a warranty administrator and service servant. What should I be buying to read and looking into? Any help is much appreciated and if I should be posting elsewhere I do apologize!
