What role did the Natives play in the balance of power between Britain & France?

The period you specify is the French and Indian War, also known as the Seven Years War. Native Americans fought on either side of the war, not so much because they agreed with or liked the Europeans with whom they fought; but because they did not like and were at war with the Native Americans on the other side. A little known fact is that the war in America actually began as a conflict between two Indian tribes.

Samuel de Champlain, the French explorer, had intervened in a dispute between the Huron and Iroquois Indians. Champlain fired into the Iroquois and killed two chieftains; as a result of which the Iroquois had no further dealings with the French.
