It's been said before:
- the big arrow on v1 is pointing to the right. The X-arrow is pointing to the real front (left on this image) and the pins of the FFIMU should point to the back. It's been corrected on v1.1
- the sensor board/shield has to be either powered by 5V or 3,3V, not both
- you can connect the FFIMU 1.22L directly to the 5V pin in the I2C connectors row

Since Paul wanted to create a shield that fits the needs of different MultiWii, AeroQuad and MegaPirate sensors you'll find more connections than usually needed.

on the picture 3.3 and 5v are connected , why ? does it make any difference ? does it damage anything if both are connected ?

You need power from an ESC in addition to having the FTDI power. The sensors won't read proper in the gui without power from an ESC.

I read on another thread for a different board that if you power the board with 5v from an external source than you should not connect the 5v rail from the FTDI,
I made a little adapter with the 5v rail removed there are pictures below altho it says 3v3 on the FTDI it is the 5v version,
Is this the case with the Flyduino board is it better to remove the 5v rail from the FTDI when powering from another source, can it damage the FTDI if you do connect both,
I have always used my little adapter to be safe rather than sorry

Thats True of Jussi's Shield but the Flyduino Displays as it should in the Gui with just the USB/FTDI and doesnt need any additional power

have you enabled these lines in the sketch?

/* I2C gyroscope */
#define ITG3200
//#define L3G4200D

/* I2C accelerometer */
//#define ADXL345
//#define BMA020
#define BMA180
//#define NUNCHACK // if you want to use the nunckuk as a standalone I2C ACC without WMP

/* I2C barometer */
#define BMP085

/* I2C magnetometer */
//#define HMC5843
#define HMC5883
