They usually do whats called Multi-Lateral Peering which means they connect to a public switch and peer with other providers who have "Open" peering agreements. Cogent does indeed buy transit, from a couple providers in a couple of datacenters. If the packet you send down their glass can not reach a "peer" on their network it will go out the transit pipe that cogent pays big money for (like any of us would, UUnet, Qwest, etc etc). Is this a good or bad way to provide bandwidth? Thats up to you to decide. If it was my packet I wouldnt want someone trying to pimp it out all over the country before deciding it needed to go out a costly loop.

I think reason a is your biggest issue.
As for peering with others at places like PAIX - MAE East - MAE West, I dont think that is necessarily bad. It is usually to dump off traffic destined to the peer's network directly.
