I don't realy exactly understand what you mean... but do you mean that:
1. You have already edit with (visudo) the needed file and changed the group wheel) to be able to sudo ?
2. If a user logs in, and is member of the wheel group, it should be able to "sudo su -" and type HIS personal password (not the one root is using) he/she should be able to sudo.
Hope this helps
