Org is often loaded before opening any .org files.  This depends on your
setup (i.e. your init file).  In your init file if you do something
like:

  (require 'org)
  (my-custom-stuff)

Org is already loaded by the time Emacs starts.

Yes.  This version of Org mode has variables that are not present in the
latest Org.  So in the customise menu you see a mix of all.  You can
verify this by doing `C-h v org-export-latex-classes RET'.  The help
buffer should tell you which file defines the variable; if I am right,
it should point to the Org bundled with Emacs.

There is an expreimental recipe by Achim to kill these deprecated
variables.  You can find it here:

<https://github.com/suvayu/.emacs.d/blob/master/kill-old-org.el>

Note that the above snippet should be loaded before you load the latest
Org: see lines 16-18 in

<https://github.com/suvayu/.emacs.d/blob/master/init.el>

Hope this helps,
