We have it connected to the analog breakout, but we're having problems getting a reading, so I'm not sure if that is due to a bad connection, or just a programming problem.

I2C is a serial bus, so you send and receive messages that contain multiple bits, giving you the range and resolution you need for the accelerometer.
