Sounds like a bit of a mother lode - good cache!
Imagine this scenario: We take the guy down and break their code along with it. Keeping him in place, we get a heads up on what's being planned. We delay the transmission of orders by say a couple of hours while we pass it along to our guys. We get names, dates, and places of where to pick these guys up. We spring the trap and scoop them up. When releasing details of the ops to the press, specify that we got our info from one of the guys we picked up. We begin the process of undermining al Qaeda from within by making them question just how loyal their operatives are. They'll be more worried about their own skin than they are the cause. Sooner or later one of them will rat out the top guys to save their own ass.
