I can just echo what others have said above. At first there was a DNS (do not smoke) shelf for aging full boxes and a shelf for stuff in my current rotation. But....I'm approaching tetris territory where I'll just have to put stuff where it fits regardless of status. I will, however, try to keep the stuff I'm currently smoking from as accessible as possible. I don't want to take out 15 boxes just to get at my cab of Partagas Shorts once a week.
Point is, you can develop a system that will work for a while, but if you follow in the footsteps of so many members around here you'll end up with a totally different system or no system at all!
