That's one way of doing it, which I have seen used on RedHat
distributions (and that I have implemented on my machines). Instead of
having a default umask of 022 and setting the primary group of new users
to "user", you set the umask to 002 and have a separate primary group
for every user (usually with the same name as the user). This way,
shared directories can be set up as you described, and files and
directories are created with 0664 resp. 0775 permissions.

But if you haven't set up your environment for that, the easiest
solution is to use POSIX ACLs (see "man acl"). Set a default ACL of:

  default:user::rwx
  default:group::rwx
  default:other::---

on the (empty) shared directory, then copy over your files.

You might have to enable ACLs in your kernel and /etc/fstab, and to
enable the "acl" USE flag (and re-emerge affected packages) for this to
work.
