In item 1, what if the referee did not stop play when notified, but waited until the end of the rally? In this instance, the receiving team had the improper libero, and they won the rally. So, is it a point for the receiving team (on the rally), and then a "loss of rally" for the improper libero, everyone rotates and we start with the next server? Or, is it a "mind change" and the previous rally gets awarded to the serving team and the same player who served continues?

It is the latter (Mind Change).
