For 1) I use folder and file naming myself rather than NFO so I can't help you more, but if it fails on such a large scale you should submit a bug with an example as it's obviously not normal behavior.
2) I understand what you mean,but I would disagree, usually it would get in the way for me (whatever it identified or thought it did was wrong).
4) The log will be on the server, admin, logs. There won't be a manage my upload though, it's a client thing and the current client does consider that outside of its scope.
Personnaly when needed it's download then use Vlc when I want to watch.
