Arduino + Accelerometer + Gyro + Bluetooth

I am very new to arduino and this is my first project in this field. I wanted some advice on what materials to buy before I actually start my project. My project consists of building a wireless device which will send its orientation info to a computer.
This device will consist of an accelerometer and a gyro interfaced with arduino board. Arduino should be able to read the sensor values and send this to a computer via a bluetooth module.

Ok that is realitivly simple. Does your computer have built in bluetooth your do you need a BT dongle?

your choices of parts are good, and I dont think you need solder the silver mate to the arduino. It should have pins that you can just run wires from into the arduino.
