The PS3 does not charge game controllers when the PS3 is turned off even though you leave it plugged in because when the PS3 is off it is completely off. The same is not true for controllers which will continue to remain on when you turn the PS3 off unless you go to the PS3 setting and set it to automatically turn off the controllers. The other accessories should work just like the controllers.

The PS3 uses Bluetooth controllers and both the PS3 Move Controllers and the Dualshock 3 Controllers are Bluetooth. If you buy a wired controller it will not really be PS3 but any PS3 controller works on any PS3 even if it is not original PS3 equipment
