Stephen,
not knowing what exactly is in your .emacs already, I would suggest  
adding the line

           (setq auto-mode-alist (cons '("\\.tex$" . tex-mode) auto- 
mode-alist))

as close to the end of .emacs as possible (so that it doesn't get  
overridden by other associations - the order of these things matters).
