One thing though... I'm able to get the item index but I can't seem to be able to get a MenuRef.

MenuRef ref; error = GetEventParameter( event, kEventParamMenuRef, typeMenuRef, NULL, sizeof(MenuRef), NULL, &ref );

I get an -9870 error The piece of data you are requesting from an event is not present.

I believe the menu ref is actually the direct object in the event, so you should do something like this:

MenuRef  theMenuRef;
OSStatus result = GetEventParameter (theEvent, kEventParamDirectObject,
    typeMenuRef, NULL, sizeof (MenuRef), NULL, &theMenuRef);

One of the best places that describes the various carbon events (e.g. parameters along with their types) is the header itself:

Carbon/CarbonEvents.h
