Nikon calls it VR (vibration reduction, I believe).
And the 1/focal length only for 35mm film, so with digital you have to use the "35mm equivalent" rating of the lens. Simple rules of thumb can get so complicated..
One of my tricks (since my camera will do it) is to put the camera into the fastest drive mode it can be, and just hold down the shutter and take several shots while trying to hold as still as I can. Usually one of the middle shots is the one with the least shake. You can also (if your camera allows) use the shutter timer function to reduce shake- since pressing the shutter button usually moves the camera button, if you put the shutter on a 2 second or 10 second delay it'll let you relax and get the shot. not as useful for shooting people, but on landscapes it works pretty well.
