- disable access to the grub-shell through enforcing a password (maybe
through using a password stored in shadow)

Basis support is there see
https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/392158 and also
http://grub.enbug.org/Authentication
But please note

Just configure a superuser and a password for it and command line access
requires a password.

- make grub.cfg readable only by root

grub-mkconfig does that if there's a password line in the generated
grub.cfg

- encrypt the password in grub.cfg

Work in progress

- describe the problems with grub-shell LOUD AND CLEAR on every admin
and security-page of every handbook, faq and such.

That's not our business.
If you _really_ want a secure system you need to encrypt everything
except /boot
LUKS support for GRUB 2 is in work too by the way.
