A+ or no A+, that is the question.

I am presently working as a CSR for a software company, and working on my Degree in Computer Science. I dont have any certifications yet and because I dont have the dicipline for self study, I am going to be trained at a IT school in here in town.I had planned to pursue A+, and Network+, but I have about 7 years of helpdesk and onsite support experience, therefore, I am thinking that it may be better to go for Network+, and Security+ rather than spend that much money on my A+. I think that my work experience would validate that I have hardware and software support knowledge so why bother with the A+? My long term career goals are to work in network administration. Any thoughts?
