The ownership of the mount point is irelevant and has no effect on the
ownership of the mounted file system.

You need to change the ownership of the *file system* root directory

Mount the ext3 filesystem and *then* change the owner and group.  Of
course, whatever you set it to will be whatever it is on any other Linux
system the volumn is mounted on.
