In some way, yes. X will generate configuration data dynamically
(auto-detect), but will not write an xorg.conf file to be used
later on. "X -configure" will do that.

Works for most things.

Only for the few things where auto-detection magic does not work,
or where you intendedly want to "hard wire" things and summarize
X settings in a central location. To do this, the auto-generated
file is a good starting point, but in many cases, can be stripped
off of many lines.

Yes. It should work the same for keyboard language definitions.

That's a valid location, but X will also use /etc/X11/xorg.conf
(even with partial content) if it is present. In fact, there are
other locations; you can find them in "man 5 xorg.conf".
