Barry,
Here's how I understand it:
Ep Never-going-to-air - "Echo" - Written and directed by Joss. Now aborted.
Ep 1 - "Ghost" - Written and directed by Joss. Notable for Paul's punching things scene, which goes on forever. And non-Faith on a bike.
Ep 2 - "Gray Hour" - Written by the show runners, not sure who it was directed by. There's a complete recap of how it looks on my website.
Then it starts to get confusing, as episodes are being shot out of order - or, to put it less politely, eps will get shifted around.
There's "The Target", which I believe is Steve Deknights ep (the one the network actually like), Stage Fright (the musical ep) (with a plot involving an over involved fan almost killing the thing they're a fan of) (shut up), "Man on the Street" (directed by David Soloman), "True Believer" (written by Tim Minear) and "Echoes".
