Ok. So,
1) no.
A) every creature must activate during the action phase, this mechanic is what makes passing work as well as it does. Each player must take an action in turn unless the opponent has more actions available than you, In which case you may pass until the available actions are even. For this same reason one cannot pray to ready Alfiya and then not act wth her so as to gain a double activation next round.
B) no, the conditions themselves dictate when they are removed, so if you must remove the daze after acting (or the like) you MUST remove the condition. Galvanize works best on burn, rot, weak, tainted, etc.
2) it stays on the creature providing the +1 melee. If its dispelled the bonus also goes away.
Hope i was helpful
