I have minimal knowledge on RP rooms, but I can give you some kind of ideas:
*power systems (reactor and all that) are normally in the center of the design
*hospital pretty close to the hangar, doesn't have to be central, because of injuries coming off the hangar
*lifts in the center-ish region, because it's normally part of the central support frame, like with skyscrapers IRL
*comms and command go on the extremities because they want to see and know a lot. Serious :p
*recreational rooms on the outside! loads of big windows is key I think
*as far as I have known! even in RP, fill space with maintenance, apartments, tunnels and cool pipes
That's all I got
Edit: may I also direct you to
