I would keep them on YouTube. Since YouTube is owned by Google, they rank their videos higher on Google higher searches so you don't want to lose that. I agree with Eric. If anything, keep them in both places.

RE: Should 301-ed links be removed from sitemap?
We have had a problem with this ourselves. We put a 301 redirect on our domain when we were building a new site (went from new. to www.) and search engines are still crawling the new. domain. Bing webmaster tools registers it as an error because they can't find the old site. I would lean toward removing it just because your users are probably being redirected somewhere they wouldn't necessarily want to go.
