I would highly recommend getting the A+. Its an easy test, and it seems to be valued a good deal in the industry. I was actually brought into my current company over others because I had just gotten mine before I applied. They considered me much more after they knew I was certified in what they wanted to achieve with the position that was open.
Just my two cents, but its worth your time. Like I said, its easy and reading the books was interesting because PnP replaced a lot of the material that was covered, stuff that helped me out later when I didn't think it ever would.
