This ability affects only creatures that are attacking at the time it resolves. It won’t affect creatures that attack later in the turn.

If the permanent is already untapped, you can’t activate its {Q} ability. That’s because you can’t pay the “Untap this permanent” cost.
2008-08-01:
The “summoning sickness” rule applies to {Q}. If a creature with an {Q} ability hasn’t been under your control since your most recent turn began, you can’t activate that ability. Ignore this rule if the creature also has haste.
2008-08-01:
When you activate an {Q} ability, you untap the creature with that ability as a cost. The untap can’t be responded to. (The actual ability can be responded to, of course.)
