Regarding the religion of the Founders, many of them weren't (and aren't today, in some circles) considered true Christians (Roman Catholics, Unitarians, members of the Church of England, etc.). Moreover, Franklin and Madison - deists - were two of the key architects of our government. Much of what we consider of our classical Federal government comes directly from them. Even then, the way the Founders (and colonists) viewed their religion was far different than modern Christians. The Constitution is a secular document for a reason.
Regarding the Iroquois Confederacy, while our government has acknowledged it as an inspiration for our own Constitution, there's controversy surrounding its actual role in the creation of our document. Namely that much of what's presented within doesn't actually match up all that well to what our Constitution became. Our government, and, perhaps, more specifically the way in which we govern is far closer to the British system than anything the Iroquois did.
Of course, if you have any real questions on this, you could always email my old professor.
