Which version of the default code are you using? Version 2.2 uses the red and green PWM feedback LEDs to help in centering the joystick trim. Version 2.4 flashes the red LEDs each second when there is no communication with the CMUcam.

right now we only have 4 speed controllers hooked up to the 4 cim motors. we are using the two pwm y-cables to hook up the speed contollers to the FRC Robot Controller in ports 1 and 2.
That's appropriate.

all the lights on the speed controllers are orange, and when we go forwards they change green and red when when we go backwards. any ideas how we can fix this? thanx
Nothing needs to be fixed. That's how the Victor indicator LEDs are supposed to work. They flash yellow/orange when there is no PWM signal, they go solid yellow/orange when the PWM signal is in the "neutral" deadband range around 127, they turn green at high forward control, and they turn red at high reverse control.
