For your understanding, you can do a simple test.  Start emacs without
the add-to-list line.  Then evaluate these:

  (featurep 'org)
  (featurep 'ox-latex)

You will get t for the first, nil for the second.

Now try to find the variable org-latex-classes with C-h v.  You will not
be able to find it.  Now load ox-latex with either load-library or by
evaluating (require 'ox-latex).  Try the above evaluations again, you
will see t for both, and when you try to find the variable with C-h v,
you will succeed.

AFAIU, the exporter loads enabled backends when you do the first export.
So when you modify a variable that is defined in an unloaded module, of
course this does not work!  Hope this makes the problem and the
resolution clearer.

To get some hints about doing things right, I would point you to my
setup: <https://github.com/suvayu/.emacs.d/blob/master/org-mode-config.el>

Hope this helps,
