As I'm not sure whether the default installation of Emacs gives any useful
font-locking for TeX or LaTeX files, I'll tell how I installed it for Emacs 
19.27. You will have to put the following lines into your .emacs file:

----- .emacs
; force loading of the font-lock package
(font-lock-mode 0)

; specify the colours and underlining of the different standard type-faces
; (In used colours because I really like the 9x15 fixed font which doesn't have
; sensible bold or italics)
(set-face-foreground 'bold  "firebrick3")
(set-face-foreground 'italic "turquoise4")
(set-face-foreground 'bold-italic "blue")
(set-face-underline-p 'underline nil)
(set-face-foreground 'underline "blueviolet")

; bind the standard type-faces to the font-lock faces, some already have a 
; sensible default
(setq font-lock-type-face 'bold)

; the following list specifies that strings matching one of the regular 
; expressions should be rendered using the font-lock-...-face that follows it
(setq tex-font-lock-keywords
'(
 ("\\(\\\\\\(begin\\|end\\){[a-zA-Z0-9\\*]+}\\)" 1 font-lock-function-name-face nil) 
 ("\\(\\\\\\(.\\|[a-zA-Z@]+\\)\\)" 1 font-lock-keyword-face nil) 
 ("\\\\def[\\\\@]\\([a-zA-Z@]+\\)" 1 font-lock-function-name-face t) 
 ("\\([^\\\\]\\|^\\)\\$\\([^$]*\\)\\$" 2 font-lock-string-face t)
 ("\\\\\\[\\(\\([^]]\\|^\\)*\\)\\\\\\]" 1 font-lock-string-face t)
)
)

; tell Emacs to use tex-font-lock-keywords for font-locking of TeX/LaTeX files
; you can add more settings you wish to take effect for TeX/LaTeX files only
(defun do-tex () (interactive) 
  (setq font-lock-keywords tex-font-lock-keywords)
)

; tell Emacs to do something special whenever you load a TeX or LaTeX file
(add-hook 'tex-mode-hook 'do-tex)
(add-hook 'latex-mode-hook 'do-tex)
----- end .emacs

If you've added these lines, quit emacs and start again. Then load a TeX 
or LaTeX file and put the buffer in Font-Lock-Mode with the command 
font-lock-mode. If you don't want to change your .emacs file immediately, just
turn on font-lock-mode and see whether the Emacs default installation suits
your needs.

Deep breath.... that's it. I hope this helps.
