Kris,
the right hand button under your thumb when taking shots has a magnifying glass with a + symbol on it. This is the zoom button when reviewing photos, and is used to select AF points when taking pictures.
If you press the AF select button when shooting then all of the AF points in the viewfinder will light up, and by using the scroll wheel behind the shutter button then you can select which of the AF points you want to use instead of all 9 at once. Once the desired spot is highlighted then half press the shutter to set it.
I have mine set on the center spot as a standard. I focus on the point of interest using the center spot, half press the shutter to lock the focus, then reframe and fully press the shutter.
If your point of interest is staying on one place, then you can select a focus point which is closer to it and use this to focus, this requires less reframing between each shot.
e.g. when taking portrait shots of people then you would go for the extreme right focus point, then rotate the camera to a portrait position, placing the focus point directly over the eyes of the subject.
Restricting the focus points also makes the AF faster, as the camera is trying to balance less information, and by going for the centre spot it is ideal for panning aircraft, which generally fill the centre of the frame.
