Try to set your recording settings to not record audio, and to always make sure to turn the sound off on your video layers.
The sync was really bad, I would have just waited for the ram thing to work again (you can ctrl+click and hold to hear audio to make sure it's syncing to the right thing).
I know you made this edit in like a day or two, don't rush it, take your time with these and learn new stuff or you won't improve at a good pace.
