Given this set of circumstances, what types of assistance would a
commercial-rated pilot be able to offer assuming she is not rated on
this type aircraft? I would guess-communications with ATC primarily.
What else?

The same things any non-pilot could do: move levers and buttons when the
captain asks her two, read checklists, communicate with ATC, etc. It helps a
bit if she has piloting experience, but that doesn't mean that she will be
doing anything that _requires_ piloting experience.
