Question is whoolly for breadth. Thanks for your comments and insights.
Files and directories have permission sets for the owner of the file, the group associated with the file, and all other users for the system. However, these permission sets have limitations. For example, different permissions cannot be configured for different users. This is where ACL's are used.
These links might help (these also address the umask issue):
