You are right. The two other files are just links.

Not needed. If sane-find-scanner detects the scanner (as user), the
permissions are set up correctly.

The snapscan backend looks for "/dev/sg0" not "/dev/sg1" or
"/dev/scanner" for some reason. Check snapscan.conf (somewhere in
/etc/sane.d/ or /usr/local/etc/sane.d/) and change /dev/sg0 to /dev/sg1.

Current versions of sane-backends don't have this hardcoded path so
I'm a bit surprised.

Please also have a look at man sane-snapscan.

Bye,
