To add to point 5, it seems to be best to consider adding flaps 2 only after you've slowed below 200 knots. Flaps 2 doesn't add much more drag so if you're above 200 knots and go flaps 2 you put yourself in a corner where you no longer have spoilers to slow down and you can't go to flaps 3 until you're below 200 knots. Might as well get into the flap 3 zone before even adding flaps 2. Just my 2 cents though.
