"Deal 2 dmg to target unit you control. That unit gains 2 power until the end of the turn." If I use this card on a unit with toughness 2 or more so that unit doesn't take the damage, does he still get the +2 power? I was thinking yes because there is no "then" preceeding the +2 power wording. Am I correct?

Yes, and you would be correct even if there were "then".
