I don't know the command `a2ps-buffer' -- do you mean `ps-print-buffer'?

You can change the command from `print-buffer' to `ps-print-buffer' like
this:

   (setf (nth 3 (assoc 'print-buffer tool-bar-map)) 'ps-print-buffer)

(save-excursion
  (set-buffer "*scratch*")
  (make-local-variable 'kill-buffer-query-functions)
  (setq kill-buffer-query-functions
	(list (lambda ()
		(if (buffer-modified-p) 
		    (y-or-n-p "Really kill buffer? ")
		  t)))))

Why not?  This is exactly what they're meant for.

You can set `user-init-file' in your site-start.el file to tell Emacs
where to look for .emacs.
