FactCheck.org has an annotated (sourced) timeline of all events in the Plame Leak scandal.
FactCheck is a project of Annenberg Public Policy Institute. It was founded by former CNN reporter Brooks Jackson. It came to prominence during the 2004 Presidential campaign as it blew the crap off either candidates false claims. Dick Cheney referred to it during the VP debate as FactCheck.com prompting the owner of that site to redirect people to a George Soros page ripping Bush and Cheney apart.

It walks through the history in a clear way and helps to remind us that a subplot in all this is that someone falsified the yellow cake documents in the first place. Perhaps Fitzgerald if finding that out too. One can only hope.
