In simple terms:
Gain: Boosts the sensitivity of the camera's chips allowing more light into the camera in low light conditions. Typically adds noise/grain to the image.
Iris: Controls how much light is allowed through the lens. Closing the iris makes the image darker. Opening the iris make the image brighter.
White balance: Adjusts the camera to see white as white and not another color. Once the camera sees white properly other colors will be seen accurately by the camera. You typically white balance on something that is true white. However you can play with the color of your image by using other colors to white balance.

I don't know what "automatic zoom" is, but there is a setting on the HVX (and DVX) to do "Auto White Tracking" in which the camera adjusts the white balance on the fly (if I understand it correctly). I never use it and I don't think it's recommended. Probably best to white balance before the shot. BTW, if the camera is not properly white balanced, you can generally tell. All the colors will shift towards yellow or blue or green. Also, Jim's explanations are excellent!

There are no stupid questions! Only stupd question askers.
Just kidding.
Yes, a white piece of paper will do the trick. Make sure, however, that it's accurately reflecting the light in the room and you're not just shoving the poor thing into the camera's face. You want it in there filling the frame, but not blocking the actual light.
