R/C Car with Arduino

Hello! Thats my first post at this forum and I'm already asking for help and advice.

I can start with saying that I don't have big experience with Arduinos. Now i decided to start a project where I will be using one of these, so thats why Im here and asking for help.

What i want to do is, to buy a relatively cheap R/C car and I would like to be able to steer it wirelessly, with help of bluetooth with an Playstation 3 controller(and even PC).

Here comes the list of things I looked at and consider buying:

1x R/C Car
1x Arduino Uno Rev 3
1x Seeeduino Bluetooth Sheild (SLD63030P)
+
of course wires and soldering stuff.

As i said i basically don't know anything, so any advices are welcome, do i need some more things? I've got the arduino, i've got the bluetooth sheild which will recive the bluetooth signal from the ps3 controller, thats what i think, is it right?

Best regards!
