That calculation requires the mass of the moon. How is the mass of the 
moon determined?

You'll find that if you replace the mass of the moon in the gravity 
calculation by the expression used to calculate the mass of the moon, 
then G cancels out.

So G does not actually appear in the calculations of the moon's gravity, 
and its value, whether accurate or not, is irrelevant.
