Sounds like you want to recreate SharePoint. I don't think there is any way to add meta information when uploading attachments and no way to force the addition of labels. These are advanced file-repository features and Confluence simply isn't that.
Your best bet is to require your people to title their docs with that info or at least require them to properly label the attachments.
