Correct way to charge rechargeable devices (iPhone, laptop, toothbrush)?

I've just been told at the Apple store that it's a bad idea to keep the iPhone plugged into the power for long periods when fully charged, and that if possible I should really only charge it when it tells me to (ie. when the battery is almost dead).

My 2-year old iPhone loses a charge very quickly, so I have it recharging whenever I'm near an outlet. I'll be getting a new iPhone shortly and would like to know what the optimal charging schedule should be. I'm also wondering if other rechargeable devices that are ordinarily constantly plugged into the power, like my electric toothbrush in the bathroom, or my laptop in my home office, should always be disconnected until the battery dies.
Or is it fine for the battery to be run dry only once in a while, and otherwise constantly charging? And if so, what is once in a while, and does the rule apply to all rechargeable batteries?
