The first 3 sets of values are are the raw accelerometer values. The 2nd set of 3 values looks to be the yaw/pitch/roll or Euler angles of the gyro.
The raw values for the accelerometer don't mean much. I think the sensors are 16 bit, so a number between 0-65k. Divide that by the G-range of the sensor. By default I think it is 4. Anyway, the DMP example has an option to enable real-world acceleration and/or readable acceleraction in G's instead of raw values. Read through the example code, you just have to un-comment a #define variable if I recall correctly. If you post your code, I will point it out for you.
