You would have to do each LED individually; there's nothing that will get all 7 at one time. (Or you could just handle setting/reverting each as the actual event that the LED corresponds to happens--that's probably what I'd do, then you'd be unlikely to have a reason to just "un-set" them all at once.)
Yes, the LEDs should revert to normal mode when all status LEDs are not set, regardless of whether the switch is on or off. (Though if it's off, this would likely result in none of the LEDs being on anymore, so if all of your status LEDs are also off, the visual difference could be nothing.) That being said, if you notice any oddities, it's possible I missed something in the driver, so let me know.
