I'm guessing you're using it with some micro controller (Arduino?), so I would connect both GND pins on the GPS to GND on the micro controller board, and '3.3V' and 'VBAT' to the 3.3 DC output on the micro controller board (note that this means that the GPS will be doing a 'cold startup' every time you start it up though). Lastly, I would connect the 'SDA' and 'SCL' pins on the GPS to the 'SDA' and 'SCL' pins on the micro controller board. Now you just have to program the board to do I2C communication (using the 'wire library' if you're using Arduino).
