The MOST important thing to do is to maintain coordinated flight. Maybe you could put an audible warning on the yaw string!

I don't agree. The MOST important thing is to not exceed stalling AOA. Below that, yaw (within limits) adds drag (or may help a bit - see discussions about slipping turns while thermalling) and may be less efficient; but you can still control your glider - exceed the critical AOA, and you are a passenger until you reduce it.

Airspeed indicators are required (which are indirect AOA indicators). Yaw strings or slip balls are not.
