I did pretty much the same thing on my radio. I used a separate amplifier module that had a little more umph and I am also running an amplifier for the rear 6x9's. I used the original volume pot to turn it on and off and adjust volume. I also used the radio station buttons to select the option buttons on the bluetooth module.
The tuner knob and needle still move so it looks completely stock from the front.
The bluetooth antenna is connected to the car antenna so it has really good range.
