It's hard to get into the IT industry, if I didn't have years of experience when I got layed off 2 years ago I could still be looking for a job or I would be in another industry. I got REAL lucky and landed a job within 2 months of being layed off, at that time no one was even getting interviews. I also have no certifications.
Experience>certifications
That doesn't mean don't do it, if you good at it and like it, go with you passion. A+ is a start, but it's basic knowledge, and like others said, it's more proof what you know. Passing a certificate test and not having experience to go with it is a bad situation to be in. Only companies like Best Buy require A+, but you have to get experience somewhere...
How much experience do you have?
edit:
just wanted some advice as to which you deem important.
What areas are you interested in? Networking, servers, PCs?
