Champion of Irori question

[drbrain]

This may be a silly question, but I was looking over the entry for Champion of Irori and I need something cleared up.
It says that "a champion of Irori may expend 2 ki points to trigger either his lay on hands ability (if he has it) or his smite evil ability."

Does this mean that a ki-fueled LoH or Smite doesn't consume one of my daily uses and/or I can use ki to activate one of these abilities even if I'm out of regular ones for the day?
If this isn't the case, what is the difference between triggering one of these abilities with ki and using it normally? Keep in mind I'm still a little bit new to this, I was just sort of snooping around to see what I might want to do a few levels down the road with the Paladin I'm playing.

This means you can expend ki to get EXTRA uses, on top of your normal number per day.

Oh that's fancy. Makes me less scared of taking Radiant Charge as a feat later.
