That shield use HC-05 bluetooth module, so yes it's possible to upload sketch to your arduino with it, if the RX/TX of the BT module connects to TX0/RX0 of the Arduino Mega.
But there is more to do, read this carefully (especially the AT commands to use).
The last schematic will not work for the Mega (at least it didn't work for me). You don't need R1 or R3 resistors, only R2 (I used a 10K) and the 100 nF capacitor were needed.
Good luck

the main question i have is how do i install the arduino.inf file? do i install it on the COM Port used by the Bluetooth Device?
