The best place to look is in the examples folder on the distribution disk.
There is a complete version in /Examples/binhex/binhex.lisp.  Here's part
of the relevant code that changes the icons to those associated with the file
binhex resources.rsrc. Perhaps the FAQ might be updated to point to this
example since this is not the first time the question has been asked.

; The resource file contains icon ("ICN#", "icl8", etc.) resources for the
; application (id #128) and for the documents that it creates (id #129)
; and appropriate "FREF" and "BNDL" resources.
; MCL contains a resource of type "CCL2" and icon and "FREF" resources for
; a larger set of document types (ids in the range 128-132).
    (with-open-resource-file (f "ccl:examples;binhex;binhex resources.rsrc")
      (do* ((id 128 (1+ id)))
           ((> id 132))
        (dolist (type '("FREF" "ics#" "ICN#" "icl4" "icl8" "ics4" "ics8"))
          (push (list (if (<= id 129) (load-and-detach type id)) type id) 
resources)))
      ; We don't want a "CCL2" resource ...
      (push (list nil "CCL2" 0) resources)
      ; We -do- want a resource of type binhex-file-creator ...
      (push (list (#_NewHandle 0) binhex-file-creator 0 "MCL Binhex Example") 
resources)
      ; Grab "BNDL"(128) from our resource file, replacing MCL's
      (push (list (load-and-detach "BNDL" 128) "BNDL" 128) resources))
    (catch-cancel
      (save-application path :init-file nil :toplevel-function #'binhex-startup
                        :creator binhex-file-creator :resources resources 
:excise-compiler T))
    ; in case the save is cancelled
    (set-menubar *default-menubar*)))
