who found the committees of correspondence to share ideas and information about challenging the british laws

I believe it was Samuel Adams:

To clarify what those committees were: The committees of correspondence were shadow governments formed at the beginning of the American Revolution; eventually they superseded the colonial governments.

France played a key role in the american revolutionary war (american war of independence; 1775–1783). motivated by the ideals of the new nation which were inspired by the french enlightenment, as well as its long-term rivalry with britain and so as to avenge their territorial losses during the french and indian war, france secretly began sending supplies to the americans in 1775.
