The camera_info directory won't exist until you calibrate the camera in the kinect. See here for how to do one form of that. The freenect driver uses a default model if you do not perform manual calibration.
If you are interested in just the depth data, you do not need to do camera calibration.
If you want to use the RGB camera combined with the depth data then you could do the various calibrations to try and improve the data, but it is not strictly necessary. If you want to use the RGB data for image processing, then you should do camera calibration to get a more accurate model than the default model.

This is a warning, not an error. Do you get data on the output topics?
