If you are asking how to change what the middle button does when using the GUI, it depends on the window manager. With KDE, this is controlled by LookNFeel --> Behavior. > 2.

There may also be an option to disable the touch-pad when you have another mouse plugged in. (This may only work when using a PS/2 mouse.) It should also be possible to use hotplug, udev, or HAL to have the system ignore the touchpad when the USB mouse is plugged in, but it will take some research. Basicly, you will need to change the /dev/mouse symlink when the USB mouse is plugged and unplugged. I am not sure about the mouse type...
