When I start Skyward Sword (its the only MotionPlus game I have, others that use it are probably similar) it always asks me to lay the MotionPlus controller on a flat surface for a bit before it starts, then it asks me to point the controller at the center of the screen and press A. I don't have to do this for games that don't use MotionPlus, so what exactly is happening here?

The original Wii controller contains just an accelerometer, so it is only able to capture simple movements, like up/down. Wii MotionPlus contains a gyroscope that captures more complicated movement. From Wikipedia:
Laying the controller flat initializes the gyroscope so that it knows where position 0 is, so to speak, which then allows it to detect when and how far it moves away from that position.
