The best two things you can do on your maiden voyage are:
Take Notes! No kidding. Bring a pad of paper or two and make lists of what you forgot from home and what you'll buy for the next trip.
You are right to look for arrival and departure lists and there are lists on FR and other forums from which to borrow. Here's one site
with more lists than you would care to use.
Eventually, you will want to make your own. Think like a pilot. There are plenty of stories by people who "wing it" and later regret it because they forgot something important. Its very easy to forget one of the many things you need to do when you are first starting out.
But mostly just have fun! Its all new to you so enjoy!
