I'm not familiar with the camera, but can you check your camera settings and see if they match your easy setup in fcp. You can usually see your camera settings by activating the display function on the camera. Interested in particular with the frame rate. Not all formats are compatible with fcp.
Also, the audio file you have in your timeline is NOT a suitable format for fcp. This is a heavily compressed format and needs to be converted to a 48k 16 bit aiff before importing into fcp. Although fcp will allow you to import many kinds of files, often they are not suitable and will often cause problems down the road.
