As far as i can remember the 30D cannot do wireless. Get a long usb2 cable, and install the drivers for your camera. You will need software to handle the files, you can use the one that comes your camera, or if you want to invest some money maybe get DSLR remote pro (windows only) or C1 Pro (mac and PC).
I usually use c1 pro, which can apply a specific colour toning, and crop as you shoot, which can be very useful if you have an art director sitting there looking at each shot.
