I am going to go for the A+ cert before the new year just to get a little bit of a start and try to get in somewhere (anywhere!) to start working in the IT field asap
If you're looking at getting some industry certs to start of with I would suggest going for one of the MS ones first rather than a CompTIA cert. In my experience they're cheaper, more interesting (less basic) and are worth more as far as employers are concerned. By all means go for one later on, maybe the Security+, Network+ or Linux+. A+ is very basic hardware/software maintenance, the sort of skills you tend to pick up after a couple of PC builds, whereas the MS certs demonstrate a high level of proficiency with (unfortunate but true) the dominant industry OSs.
As someone else suggested, I would definitely look at setting up some sort of lab to play around in also. VMWare is very useful for this if you don't want a load of old PCs lying around.
