@Whitey My site is a medium site with 100,000+ pages from a small number of dedicated experts on a couple of related, specific niches, and we add hundreds more all the time.
None were cut or had their content modified in any way as a result of Panda. They're all long form content (more than 250+ words many 1000+ words... the only exceptions being some image galleries... also properly formatted) and they're all relevant to their topic.
All of the things you have mentioned have been done, always have been done, and are always being done, since it's the very nature of our site to do those things.
