I'm not sure if that Bluetooth module is able to pair with a PS3 controller, usually you need a USB shield and bluetooth dongle to connect to one. You definitely should do some research on that and see what the specs of that module are and what it is capable of doing.
Just looked in to this, and you are right!
With the one I picked, i could connect my phone to controll it, but not much else.
To connect the PS3-controller, I need to be able to set a static MAC, something the smaller device didn't support...
Another question for further expansion of the project, does it matter in what order shields are stacked?
The only thing I could find is that as long as the pins are not used by another shield, you are good to go! Id this true or is there something else I need to know?
