No question asked in sincerity is dumb, and neither a lack of understanding nor 
the desire for increased udnerstanding is a fault.

Not quite. -dbluetooth:12:34:56:78:9A:BC

The pincodes file isn't maintained by the system - it's maintained by you. It's 
where you associate your devices' Bluetooth device addresses with their PINs. 
If the system doesn't know the PIN then it tries to look it up in the pincodes 
file.

>Will the device have the same Bluetooth address every time the computer

Your device will always have the same Bluetooth device address. That's the 
simplistic answer, anyway. The accurate answer is that a Bluetooth device 
address is like an ethernet mac address. In other words, it's associated with 
the Bluetooth hardware in the device. If that hardware ever fails and is 
replaced then the Bluetooth device address will change to the one associated 
with the new hardware.
