How to read a gyro/accelerometer

I recently purchased this MPU6050 GY-521 breakout board. I tried it with my Arduino Mega using this Arduino sketch provided by official arduino.cc.

Man, it gives this weird output!!!

(This is only a part of it, it gives this king of output continuously). I know for sure, only the temperature reading is meaningful. But what are those values given for acceleration and gyro readings??

OK, It says those are raw values. If it is so, then how can I convert them into meaningful values. Hoping it can be helpful (as many suggested), I also like to know how to use so called Jeff Rowberg library.

Hope there will be someone experienced with MPU-6050 module. Just give me a point to start. I have no clue on how to use the module... :(

Any help is greatly appreciated. Thanks !
