A cross bike is very useful as a Chicago commuting bike. I went from a Giant hybrid to a Soma Double Cross as a commuter and was very happy with the decision. A good cross bike is so versatile. I also use the Soma for Century rides and group rides with very good results.
The 48/39 crank-set will be ideal as a commuter in Chicago. I ran a 46/38 on my bike and never had any issue with any of the hills in Illinois.
Personally, I would avoid disc brakes. Disc brakes are ideal in wet weather and hilly & grimy terrain. Even if you commute year around, you will find cantilever brakes to be simpler/lighter/cheaper than disc brakes and the wet weather performance of disc brakes is simply not needed in Chicago, YMMV.
