Personally, I would just sync the audio, it would probably take less time, especially with a bunch of clips. If you need to move the audio track itself put another piece of audio in front and trim it back and forth and butt the track you want to use up against it. If not, then trim your video to meet up with the audio.
I know that some people use soundwaves, I have no clue how to do that, I use eye and ear to sync audio, BUT depending upon what you've done so far, that might be your best bet.
