Yes, that's one way to do things.

Why not just keep everything owned by the Apache process? Protect
access to the files through a download script, .htaccess, or some
similar way.

Even if you do change the ownership of the files you won't be more or
less secure. They'll all be access via the Apache uid anyway.

As I said - I just keep everything owned by Apache. Membership is
managed through a MySQL database or .htaccess.
