Well, the easiest way is to just use an {if} statement in the menu template itself. Something like this:

{if $usertype eq "C"}

show menu code for customer side

{else}

show menu code for admin side

{/if}

That way, you don't have to go through all the admin templates updating the code to point to a new menu.tpl. You can do the same thing with any of the shared templates.
