I'm not an expert at this!
http://www.tcpdump.com/kb/os/linux/starting-and-stopping-raid-arrays.html says "mdadm --assemble --scan" but I think that'll scan everything, and as you have one that's already working, I think you can do
mdadm --assemble /dev/md1 --scan
If that doesn't work, the above website lists how to find the UUID of the array and restart the array using that. HTH
and (b) any clues as to what the "something" was and how to avoid it?

I'm guessing the something that caused the error is the USB disconnect. I think all the rest of the log is just showing how the system is trying to recover. Does anything before give a clue as to why it disconnected? Lose wire, prying fingers? Dunno - grasping at straws!
