There's not much out there aside from models that have already been done.
As for signal flags, since she was at anchor, she wouldn't have had any signal flags flying at the time of the attack. Her riggings is pretty straightforward, signal halyards, six on each side forward, 3 lines running from the bow, one on each side of the yards, and one running to the fighting top, with four downlines running from the center line down to the bridge area. You have a support line running from the top of the fighting top to each of the yards, and several lines running aft, including a single line from the after fighting top to the jackstaff.
I don't recall if Arizona had completed her flag raising ceremony on the stern when the attack started, but I do know she had a flag on her stern after she sank, whether or not it happened prior to her sinking I'm not sure.
