The leader Words are minor actions. The correct course in this scenario is to heal both of the other guys, and then use your standard action to attack.
No, you can't.
As far as I know, all the leader words have a restriction stating that you can only use them once per round.
I only checked Runepriest, Cleric, Ardent, and Warlord tho, and I'm too lazy to check the rest. But I'm almost certain Bard, Shaman, and Artificer are the same.
