What happens during "Substep 2: Before Damage Step"?

1) Can P1 declare an attack, then both players pass priority into Substep 2: Before Damage Step, and then P1 activates Book of Moon on an opponent's monster?

2) Will P2 be able to activate cards such as Mirror Force, Sakuretsu Armor, etc in response to P1's Book of Moon during the Substep 2: Before Damage Step?

3) May you give me general examples of types of cards or specific cards that can be activated in the Substep 2: Before Damage Step.

I'm just generally confused about what happens in the Substep 2: Before Damage Step, so any help is appreciated.
