[AUCTeX] do I use auctex???

[LWF]

Hello list,

I am working on a PC with MS Windows XP as OS. Up to now I used TeXnicCenter 
and MikTeX for texing. Now I want to give Emacs and AUCTeX a try. 
Therefore I use the modified Emacs for Windows distribution of Vincent Goulet 
(http://vgoulet.act.ulaval.ca/emacs) which have several additions to GNU Emacs 
like ESS or AUCTeX. Everything works fine except AUCTeX. I can open and compile 
tex files using C-c C-f. But after importing a .tex-file I don`t see the AUCTeX 
buttons on the tool-bar. In the menu-bar there is a menu "TeX", but not 
"AUCTeX" or something similar. Therefore I am not sure if I use AUCTeX at all.

In the config-file for Emacs, which is called "site-start.el" in the 
distribution of Vincent Goulet I have the following section concerning the 
AUCTeX configuration:
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;;
;;; AUCTeX
;;;
;; We assume that MiKTeX (http://www.miktek.org) is used for
;; TeX/LaTeX. Otherwise, change the (require ...) line as per the
;; AUCTeX documentation.
(load "auctex.el" nil t t)
(load "preview-latex.el" nil t t)
(require 'tex-mik)
(mode: TeX-PDF)

(setq TeX-auto-save t)
(setq TeX-parse-self t)

;; Turn on RefTeX for LaTeX documents. Put further RefTeX
;; customizations in your .emacs file.
(add-hook 'LaTeX-mode-hook
          (lambda ()
            (turn-on-reftex)
            (setq reftex-plug-into-AUCTeX t)))

;; Add standard Sweave file extensions to the list of files recognized
;; by AUCTeX.
(setq TeX-file-extensions
      '("Rnw" "rnw" "Snw" "snw" "tex" "sty" "cls" "ltx" "texi" "texinfo" "dtx"))


Can someone help me? Is there anybody who works with the distribution of 
Vincent Goulet with similar problems?
I use the latest version GNU Emacs (23.2) and AUCTeX (11.86).

Thanks.
