Bought a 3.2" LCD touchscreen for the project yesterday, I got it from here:
Also the arduino arrived in the mail. In about 30 minutes I'm gonna go to radio shack to get the appropriate wires and a couple test LEDs/Resistors and hopefully I will have the LED's controlled from the Arduino by tonight. Unfortunately the LCD screen and temperature sensors won't be here for a while because they're coming from Hong Kong.
A couple pics of the arduino:
