That would be one of those questions I mentioned would be answered after the mission...
The tiny machines send back a long string of command sequences and parameters for optimal operations. You determine from these that the nano-bots require a genetically compatible biological host. Genetically compatible meaning that only a certain genome in the host's system would be able to bypass the collective's security measures. Obviously this was done to ensure that if they were stolen and placed in another host, they would not work. How they know what to change the body into is something that baffles even you. The coding indicates that they get a command from the host's thought patterns, which would indicate that perhaps they have programmed with templates of varying species and sexes, but evidence has shown that Four could emulate just about any humanoid with ease and change even the most minor details. How the machines are able to do this would require more time to study or perhaps getting one of the designers to explain it. Either seems a distant goal at this point.

The office remains empty for a time, the illumination is off and only minimal power is running through the other systems in here. A desk and computer console has been placed here for organic access, but the console has not been connected to the port you are now using.
Air quality indicates that the ventilation system is functional here as well as the heating, but they are kept to less than optimal conditions for personnel, meaning that perhaps they don't intend on anyone coming in for some time. You make sure to monitor any changes to indicate otherwise.
The first layer of security on the core's infrastructure is difficult to pass. There is a constantly changing code transmission that occurs at regular intervals during access. While to the untrained eye these sequences appear random, to any droid worth its Code they are in a very specific order. After a while of observing them, you are able to come up with the counter codes.
The second layer isn't as bad, having to emulate a proper access code, but this will be erased as you progress through the system and attempt to hide your trail.
The third layer proves the most difficult. As you neared this construct in the Code architecture, you noticed that it is monitored by quite a few slicing droids. Fooling them would prove impossible at best.
However, with a little extra Code manipulation, you manage to pass yourself of as a manitenance droid and thus gain low level access to the system.
This access gets you a line print of the power conduit system, where all the power goes and where it comes from. At each juncture in the line, a small blurb explains what part of the complex center that power is being routed to. This of course becomes your map. While it isn't floorplans, it's the next best thing.
Smack in the middle of the structure is the generator core, a huge facility almost as large as one of the Star Destroyers outside. There are numerous personnel stations across the center and even more work stations, as would befit a command center. A large number of communications antenna arrays dot the surface of the structure. This would appear to indicate that each one covers only a certain part of the center. You could access the comms system from any port, but to make direct use of the antennas, you'd have to go where their power conduits are held.
There are of course power relays along the pathways as well. Taking out any one of these could shut down an area of the complex for some time as backups are put into place.
You count eighteen major hangar bays that are powered in the center with at least twice that many smaller ones, presumably for close range personnel transport. There are also twelve docking and refueling ports for capital class ships.
The main command 'bridge' seems to exist near the very top of the structure, with numerous subcommand stations located throughout the facility. If Dofina is as high a priority target as it would appear the Imperials have marked her as, she would probably be held near the main control center. This same control center would also appear to hold the main flight command center.
There are very few personnel airlocks, except near all of the hangar bays. It could easily be assumed that any EVA suits would be located near them.
All in all, you have managed to put together a rather detailed, if rough, map of the center complex. With any amount of luck, it will suffice and the whole procedure will be a cakewalk. Except:
"ALERT! Intrusion detected. Improper system access. Lockdown in affect. Security enroute. ALERT!"
The warning repeats itself and you note that the temperaure in the room has begun to rise.
