To the OP:
As a CS Professor I can give you some advice:
The A+ Cert is a great place to start if you are interested in computers but are unsure where to start.
There is an old saying that reading about bicycles doesn't teach you how to ride a bicycle. This is why experience is so important.
Some suggestions:
-See if you can get a job at a computer store or in an IT department as either an intern (paid or unpaid - though unpaid will get you in somewhere sooner) which will help you immensely. You will do a great deal of grunt work but it will expose you to a plethora of technology that will help you in the long run. You can expect Windows Troubleshooting, Virii removal, hardware break/fix, simple networking troubleshooting, and much more.
-You can look at getting other Certs as well: MCSE (MCP), CCNA, CNA, CNE, and many OEMs will offer tech certs for their products (HP for example).
-College and University Degrees: A College or Trade School degree will always help you and of course a University Degree is at the top of the list.
If you are going to be in technology you have to keep your skills sharp and be diverse in your skill toolbox. At the University level, they used to push one skill per person. If you were a database programmer, you did JUST database programming. That is no longer the case.
Today a good University will teach you database programming but also how to build the server, install the OS, secure the environment, deploy clients, and be a well-rounded engineer. Companies today expect IT people to have a varied and diverse skill-set.
Lastly, keep up with technology and if you want to be competitive you will need a University Degree, some certs, and appropriate experience.

Sorry, but this is somewhat true. I am not saying you have to get new certs all the time but staying on top of technology and skills makes a world of difference. This is no different than doctors, lawyers, pharmacists, or others keep up with new information in their respected fields.
Finally, have fun! They say do something you love and you will never work a day in your life. I believe this is true. We all have are good and bad days but I love technology so I never dread work. I feel like we are always making things better for people so technology has a great place in society. I'm not saying there aren't other great vocations in society, I just really enjoy being apart of technology.
Good Luck!
