you pull back on the stick to augment the
angle of attack, maintaining airspeed. Everything's good so far?

No, not really. When you pull back on the stick, you will lose
airspeed. In order to maintain airspeed, you will need power. If you
also apply power at the same time as you pull back on the stick (at the
same time you are in the 60 degree banked turn) then you can maintain
airspeed and altitude.

Once you get your head around the need for power at this point, the
answers to the rest of your questions should become clearer.
