Nick - I agree about it being nice to be able to pull trains out of a yard w/o having to move them by hand. FWIW, I started out with the attached SCARM plan and ended up with the yard built as shown, with 8 sidings. Of course, mine are shorter and the curves are O-36, but it gives you an idea of what it might look like. I also used a couple of O-72 Wyes as well as O-72 switches.
One thing you might want to consider is leaving some open space between the tracks for long, narrow accessories like coal ramps, saw mill, log loaders, etc.
I also added lighted bumpers at each end and put each track on a separate toggle switch.
