Welcome to the Q&A Forum

I don't think there's any harm in submitting a new/full list, even if it duplicates past lists. The URLs haven't been removed, and you did fix the tags. This isn't like disavowing links - it's more of a technical issue. Worst case, it doesn't work, from what I've seen.

This is where things get a bit dicey - I'm not 100% sure that won't remove the main page, too (and how Google handles the trailing "/"). You might need a "/*" wild-card in the Robots.txt. Frankly, I'd ease into it with just one directory. These things never seem to work quite the way in practice that we all say they should in theory.
