The operator groupt allows its users to perform some operator tasks,
without needing them to be in the wheel group. It's like a "limited
root permissions" group. You'll find some programs that are +x for
this group (for example /sbin/shutdown).

I've often seen that FreeBSD defaults to user name = group name
for the adduser script, but I usually use the staff group, as you
do. Further fine grained parameters for user and group preferences
can be set in an environment where you have more than one user.

Why "of course"? :-)

Typical single user setting.

There are several groups that you can add your user to, but because
you're already in wheel, you don't have to (such as the "dialer"
group for ppp).

No, they seem to be "Linuxisms". :-)

No. What should happen then? How should that work? :-)
FreeBSD manages the things you're requiring through two important
files: /etc/devfs.conf (and /etc/devfs.rules) and /etc/devd.conf.
The devfs files control the virtual device file system. It allows
you to have permissions on a per-device file basis. These files are
those that are present from system startup on.
The devd file controls how the system should react if it detects
new devices while it's already running.
See the manpages for these files. Yes, they do exist. :-)
