Re: First Contact bridge concept art...
I haven't seen the extras you mention, but the full design history for FC is very well documented in the book John Eaves co-authored, it is the STAR TREK THE NEXT GENERATION SKETCHBOOK for the movies TNG and FC, there are several pages on the bridge design as I recall (every copy I get falls apart after a day, so I don't even have pages of it anymore, but it is a great reference.)
I just checked and my original rave about it from 15 years ago is still right there on Amazon's page, I think it is the only time I ever posted anything there.
Sounds like an awesome book to have, I'll try and find it.
