I want to incorporate the servo squirter into a project I am doing with an RC car. how would i be able to make this so that I didnt have to carry the computer around with me to demo the project? I am planning on using an Arduino Duemilanove with an ATMega328 on it for the RC Car to have a sweeping gun. Is there a way to combine this squirter with the Arduino without using the computer as a control mechanism?

Short answer Yes.

Long answer - you'll most likely need an extra 2 channels on your RC contrller (one for a servo to rotate the water gun, and another to use as input to the microcontroller to fire it). You should be able to take the PPM signal from the RC receiver and use it as an input to the micro. This will of course require some programming on your part.
