There aren't any plugins that I'm aware of that would show you those specific items. You can certainly find locate that information in the database, however. If you wanted to, you could even integrate those reports into a custom plugin for the admin console.
Take a look at http://www.jivesoftware.com/community/community/developer/clearspace/plugins for some sample code.
