RedAndCosmoteer Not going to lie, I haven't played the campaign in ages. Whats the mission like? I might not be of too much help but I can maybe provide some pointers.
And for docking, there's probably an actual series of docking ports. Idk if the ships have them, but some engines on the sides could help spin the ship around like Kerbal RCS ports. But then again, in game you can't really maneuver a ship in combat other than "point and click" in a direction you wanna accelerate to.
