I have been putting off A+ exam for far too long. To prove my point I have both 4th and 5th version Mike Meyers A+ books...

We have our first baby girl on the way and I was wanting to buckle down and at least pass the essential before June. May will be even better.
I have been working on PC's mostly around consumer level problems. Virus removals, image reloads, upgrades , gaming systems , home/small business networking. I have always felt I needed to really spend the time to pass the A+ regardless of most people that say you don't need it. Then again most all of those people don't have the cert. So to fill in any gaps in my knowledge I figured I need to complete this first half before my June data arrives. And then plan a few more months for the 602.
I was about ready to schedule for a date but have a few questions before I do.
1.) Legit websites to buy vouchers? I almost just want to pay at the testing center to avoid hassle/scams online. Recommended sites to purchase discounted vouchers that you know work?
2.) I heard the objectives might be changing mid year. How should I plan my course studies around this possibility? Do I sign up now for the current exam? Does this current exam get replaced at some given date with new content that I will have to hunt down with new books?
3.) Is the current revision 2007 standards? I have a CompTIA A+ 2006 (Thomson) and curious what material would be best to read. Mike Meyers 6th revision or any known new versions that just hit the shelves?
Sorry for the questions within a question. Thanks. Great site by the way. Look foward to learning this material.
