I think B5's Vorlons had living ships before LEXX.
I'm keeping quiet about B5. Don't want to stir up more ill will. I don't think I claimed Lexx was THE first living ship, only it did it before and way better than FS. It may have been the first where the show takes place primarily in the living ship though.
And that six million dollar man TV concept is AWESOME! I didn't know the series was based on a book. What a great idea. It's like how BSG took a totally inane, juvenile television series, kept the best parts, threw out the rest, and made something awesome. I've been looking for something to read just lately ...
About Firefly, I spoke too soon when I categorically stated it was boring. I haven't given up on it. What I've seen of it so far was boring and I was never motivated to watch any more of it. But I'll probably end up renting it on DVD someday since everyone thinks it's so great. Unlike Farscape: THAT I've given up on.
The thing about Firefly, it wasn't science fictiony enough to capture my attention. It seemed like the plot could have happened anywhere or anywhen. The ship just happened to be a SPACE ship and the time just happened to be the future--this is from the couple of episodes I've seen, keep in mind. I know that's kind of the whole idea behind the show, so don't scream. I'm just saying what I saw wasn't enough to make me want to see more. My Netflix queue is getting short so who knows, I may check it out again in the next couple of months.
