Luke,
Enable the Content Permissions module (part of CCK). Then go to permissions, and you'll be able to define permissions for every field individually. As a caution with this though, you'll have to set permissions every time you add a new field, or users won't be able to view your content.
With this, any visitor could download the file if he knows the url. Use the private/public options of File-system under admin/settings
