As soon as you made you deposit, you should have received a booking number. With that, you can log into the Carnival website (create a login name/account if you have not already). Once you log in, go into "My Profile" and then on "add a booking #. Once you do that, they will track how many days you have till your cruise and then you can also fill out your "Fun Pass". If you fill this out now, it saves time come embarkation day.
Then the other thing you should expect is 30 to 60 days before your cruise, you get you "docs" Bascially you cruise tickets book. You should also get some information specific to your cruise and luggage tags.
You can be as excited as you want.. that part of the fun of cruising! You may need to give her a call and ask her for your booking number. You really don't need it until you cruise and it will be on your tickets. So she my not realize you want it.
But once you have it, it allows you to go online and look/book excursions etc...
