That's what I hit through high school. "Which way to turn? Which path to take?" In the end, I went IT, because I had a natural gift for it. Now I regret it. You actually have a good head start. What you want to do is take your psychology/education background and lever that HEAVILY into IT. Slip yourself into a niche that your 'off the mill' IT person couldn't do...
As for programming or support, I've been torn, too. There's a future in both, although one that's seemingly more limited due to outsourcing and 'Cloud'. You'll probably see the numbers of IT personnel decrease somewhat, but be sucked into more centralized locations for IT and cloud 'shops' with lower pay. If you're GOOD at programming, I'd say that way can lie greater dividends overall if you can be idealistic and creative (I'm not) to come up with some hot new psychology app that makes you a small fortune. Otherwise, the path you mentioned (A+, etc.) is the one to go down. Pick a specialty, network or security, for example, and work your way into it. A lot of it is time, and a LOT of times it's dumb luck...
The only thing that limits you is your vision... Then your attitude and skills.
