Arduino Mega ADK and bluetooth


Currently I am looking to implement some peripheral functionality with an Android tablet using the Mega ADK board. However it would be nice to interface via Bluetooth rather than wired. So I was curious about a couple of things. First of all, all I am doing is outputting commands from the Mega ADK through the serial output. I was planning on then transmitting it through a bluetooth module to be received at the other end by the tablet. Also, I was thinking about buying this module for bluetooth interfacing with the tablet. So I was wondering if anyone had recommendations about my setup or some suggested hardware to try

Also I saw this one, but I am unsure if it is what I need. I know Arduino has their BT board, but I don't know if that is perfect or overkill?
