1. I recall our 'dress-up' night (not formal though) being Tuesday night - the night of the Pirate party. My brothers wore coats over their polos and khakis. Us ladies wore sundresses.
"On 4-night cruises:
First night: cruise casual no shorts, swimwear or tank tops
One pirate or tropical night (deck party)
One "dress-up night" jacket for men, dress or pantsuit for women
Final night: cruise casual no shorts, swimwear or tank tops"

2. We had a table of 7 family members last time. We sat together at one table as a group by ourselves.
"Can I request whom to sit with at dinner?
Every person in your stateroom will be at your table. At the time of booking, you can specify other people who will also be onboard. If not, assignments will be made to fill in your table. Generally, adults without children will dine with other adults, while families dine with other families."

3. The DCL website says to be aboard by 4pm. The life jacket drill is at 4:45pm. (Great photo opportunity in the fluorescent orange jackets!!) & the ship leaves port around 5:30pm.
Also:
"Since July 2008, government regulations have required guests to check in no later than 90 minutes prior to departure. The 90-minute cutoff was instituted so cruise ships could send U.S. Customs and Boarder Protection (CBP) the ships manifest (a list of all passengers onboard), and the CBP could take an hour to review it before clearing the ship for departure. "

This 90-minute-minimum only applies to those who have not filled out their forms on-line prior to arriving at the port.
