Your best bet is asking the salesperson since a lot of it is cruise line dependent.

If you just want personal anecdotes, based on the cruise that I participated in:
1) They have a person on the boat itself who helps you book things and provides information. They had a dedicated office because they make money off booking these things so it's very easy to set up.
2) The boat takes care of getting your from the boat to shore and vice versa
3) All shows were included, first come first served
4) Certain facilities have extra fees but they will tell you up front
5) Wifi wasn't included, alcohol isn't included, some of the onboard dining isn't included, though they're pretty upfront about these. The only hidden fee I experienced was a "service" charge which went towards the employees (allegedly) which they tacked on per day which you could remove if you wanted, but you had to talk to customer service to do so.
