@elainor: sounds are normal. There are two kinds of sounds, one when the AF-S motor is working, and the VR sound when VR is active.
AF-S sound is like a high pitched whine when the lens focuses, or is hunting for focus. It is a sort of dry grinding sound. Its quite soft, though how soft... unless you already know how it sounds like, its kinda hard to explain. Some lenses are lounder than others. The huge lenses are quite loud, and the cheap non-ultrasonic AF-S ones (18-55, 18-105, 55-200) are loud too.
The VR sounds like rapid clicking, sorta like if you go snorkelling and you hear rapid short clicking of the fish and crabs picking at the corals.
To differentiate the sound, hold the lens near your ear, and half press the shutter. Initially you'll hear the grinding whine, and maybe half a second later will be the rapid clicking. Once focus is achieved, the grinding whine will stop. The clicking will be continuous until you release the shutter half press.
Hope this helps.
