When I have played, we have only had a maximum of four players. Each time we have played it like this:
Player 1: Helm
Player 2: Weapons and Science
Player 3: Engineering
Player 4: Captain's map and Comms
Helm is a hands on enough station (especially if you are using a Joystick) and therefore the Helmsman has no other responsibilities to distract them when they should be flying the ship.
Weapons and Science have worked well together for us. Out of combat player 2 can scan the ships and get the frequencies of their shields. In combat, they can use this data and quickly formulate tactics for the battle. Depending on who operates the weapons, the captain may allow weapons the freedom to engage the enemy as they see fit (to a certain extent, the captain doesn't just sit back and do nothing!)
Engineering, when played most effectively, is a very demanding role. That's why we dedicate it to one player only. They have monitor power distribution, damage control and energy levels very closely. We have found that proper control of energy can greatly increase the efficiency of the ship.
Captain's map and Comms work well together. Personally, when I have played captain, I have managed to use Comms effectively to deploy other vessels in to areas I plan to head to, in defensive positions or in a safe area. You have to almost work as a fleet commander as well as the Captain. The only difficulty I found was dividing my attention.
