How did you book your cruise? These questions could be made much clearer by a travel agent if you used one.
I'm not sure you can get travel insurance if you have already paid for your cruise. Also do you have time to get expedited passports? Did someone advise you on any of these things?
You need to call either your travel agent or whoever you booked through.
