Illusion is indeed common AS knowledge. Besides Moiraine, e.g. also Alanna uses it in LoC.
IIRC, inverting weaves was taught to the other Rebel AS by Egwene, after she learned it from Moghedien. Not sure about hiding the ability to channel.

The reason why illusion was really never that much of a deal before this was because the Aes Sedai were not able to invert the weaves for them to be hidden; therefore, any woman who could channel could see that you were surrounded in a cloak of Saidar.
