Guide to gyro and accelerometer with Arduino including Kalman filtering

This is awesome, and probably just what i need!

I'm planning to create a gyroscopic platform on which i will mount a GoPro camera or a Contour camera. I will be mounting this onto a motorbike on an actual race track, so it will go through some pretty intense forces. Then i want to compensate the camera angles using e few servos. I only need to compensate for the pitch and roll at this time.

I have experience with arduino's and the coding but im not familiar with the gyro and accelerator sensors.

I do have a few questions:

Offcourse the first question is; considering the forces applied on the sensors by putting it on a motorbike. Will this still work?

and; is using a gyro and accelero enough to fully remove the drift or will i also need the magnetometer (i need the platform to remain absolutely level to the human eye)?

and; are the resulting values usable to compensate using servo's?

i will probably be using this board with my arduino:

Thanks in advance,
