The gyroscope is a digital gyroscope so you need to connect it to the SDA and SCL on the Arduino. See the following page for more information: Wire - Arduino Reference. Then connect VIN to 3.3V and GND to GND on the Arduino.

Your accelerometer is a analog one, so you need to connect X, Y, and Z to your analog inputs. And yet again connect VIN to 3.3V and GND to GND on the Arduino.
