When you're done scouring, head up the inclining ramp and then go through another door you encounter. A Fission Battery and a bunch of Wonderglue are the most valuable items you're likely to find here. Then, work your way northward into the next room, killing two more Nuka-branded Protectrons before exploring the various metal boxes on half-destroyed shelves in the room.
5mm Rounds are about the best you're gonna do here. Scour the desks for some various items, although you won't find anything too valuable. Access the various files on the computers if you want, but there's nothing here you have to read (and as for that safe on the wall, you don't have the key to open it, so ignore it for now). Swing leftward down the corridor from the lobby, killing the Protectron you run into in this next computer-filled room. Side Quest: The Nuka-Cola Challenge (Continued)
