Hey Scott,
Yeah, the Babel gaff is a big one! I'm keeping an eye out for more. But so far, I haven't seen anything. There is a similar kind of thing going on with the red rails on the TOS bridge. Some times in first season episodes, I can't name a specific episode off the top of my head, the blu-rays made it even more clear that they put red tape around the joints of the rails! Some episodes had the tape and most didn't.
Regarding redressed sets, Data's quarters was used for Worf and O'Brian. The ceiling beam that jogs down onto the side wall is the give away. You can see it in Kirk's quarters.
And I had it wrong, The Enterprise corridor sets are mostly new.
Greg, yes, I was just pointing out trivia rather then asking a trivia question!
I'm not as familiar with Voyager, so those ships I am not sure about. I can guess that one is from Species 84619, or whatever the number is.
