does anyone know where a pin diagram/schematic is for connecting the pins for a 3-axis gyro can be found? I have a triple-Axis Digital-Output Gyro ITG-3200 Breakout board with an ATmega328 chip...

Looks like the ITG-3200 use an I2C interface.  You use the Wire library to talk to it.

From the Wire library reference: "On most Arduino boards, SDA (data line) is on analog input pin 4, and SCL (clock line) is on analog input pin 5. On the Arduino Mega, SDA is digital pin 20 and SCL is 21."
