use pins 0 and 1 as normal output pins

Using Arduino Microcontrollers

I need every pin on my Arduino and I cant seem to use pins 0 and 1 as digital output pins. Is there a special script I can use for this?

Make sure you don't have Serial.begin( ) in your sketch.
Then you can use pinMode (0, INPUT); etc and digitalRead, digitalWrite without conflict.
The 1K resistor between D0/D1 and the USB/Serial adapter will act like a strong pullup resistor, so any input signal will need about 5mA of drive current to take the pins low.

I'll bet you don't need to use the serial interface pins.

You do realise that the "Analog" pins are entirely usable as digital inputs and outputs?

Even better, explain what you are actually doing. What happened to the MAX7219?
