Here is how my first org-mode file for export to pdf using LaTeX starts:
#+LATEX_CLASS: article #+LATEX_CLASS_OPTIONS: [a4paper] #+OPTIONS: toc:nil #+OPTIONS: ^:{} #+TITLE: Ett första försök att blanda in LaTeX i en Org-mod fil
#+AUTHOR: Martin Schöön
The first two rows should be self explaining and they show the syntax.
The third row prevents the creation of a table of contents.
The fourth row forces me to use the LaTeX convention of ^{something} and _{something} for super- and sub-scripts.
Line five and six show you how to define title and author.
I have never tried what you are trying to do with references so someone else must step in and help you there.
