Well, how familiar are you with this percussive/touch style of playing? I'd suggest experimenting as much as possible to get your fingers used to tapping and pulling off like hell, as well as work on transitions between percussive beats and strumming out quick harmonics. Also be sure to find all the "sweet spots" on your guitar so you know where all the various percussion sounds are on the body.

This song doesn't look like it should be too hard. Work with the style more and you'll see what I mean. It just looks intimidating if you're not used to playing like this.
