1. No hard-and-fast guidelines. Honestly, I've only ever protected a page so that only admins can edit it. Pages such as the Policies and Guidelines page or a wiki coding page can be protected that way. I've also protected my profile so only admins can edit it because of a vandalization. Making a page so that only users with accounts can edit it could be useful too. You could probably do that to any non-article page you think it would be useful for. So you'll probably know which one you want to set it to when you decide to protect a page.

2. OH, comments! Sorry, I read that wrong. I thought you meant articles. Yes, that would be fine. If  users are provoked by a comment like that, you could ask the user to give a reason for their statement, and ask the users replying to keep the debate friendly.

Now is fine if you want.
