Well, most of that I'd accept, Mark. Still, I think it's safe to say that the texts of the New Testament date from the first century, with almost certainly nothing written after 125 AD. The "canon" of the New Testament that we have today took shape beginning in about 150 AD, and was generally accepted by 200 AD. The Councils provided official recognition of the Canon as the Church took shape as an institution, but the Canon already had wide acceptance long before.

As for the writings that were not accepted - it seems to me that most just did not fit into the beliefs held by most of the Church. Some, like the Didache and the writings of the Fathers, are still in use but not considered to be Scripture. It does not appear to be a matter of bureaucratic or political suppression of unacceptable thinking - the canon of Scripture took shape before there was a bureaucratic and political structure within the Church.
