i'm not an expert but I believe you can leave INT and Fsync disconnected (there is a pulldown on the circuit board) as you are not using the SPI interface.
The Raspberry pi PIO is 3.3v max so I would definately power the sensor board (and all I2C sensors) from the 3.3v pin on the GPIO header and never the 5V.
