Yeah I play it like you got it tabbed here. Mostly when I play it I let the open strings ring (Try not to strum them again) when the 3 string parts come up. That's just how I like to play it though. You don't have to play it exactly like they do just however you like. When I mute the low E I usually place my finger tip that is barring the chord (Index) on the side of the string to mute it instead of on top. Then with the high E just roll my wrist in a way that I take pressure off of it. Since "Outside" is a slow song it shouldn't be too hard.
