I'm on my way to the same point you're at. I have everything but the phone, and being in the US, I have to wait for a friend to go to the UK to get it...
You should be able to do it with little extra software on either end... I'm running in Jaguar 10.2 now, and Bluetooth system preferences...

Their service is tops and their prices are good. Last I saw the same module was $100.
Good luck
