Alright, now for the tab.
The picking is pretty quick.
I'm just going to tab how I play, but you can fiddle around with it a bunch of ways and 
it will still sound fine.
Try to let the notes ring.  Especially the open B string.

And repeat.  Sometimes that last part with 5/4/0/0 is played one or two more times, like 
in the intro for example.
Also, randomly throughout the song, he does a hammer on on that 5 you play.
That's pretty much it.  Like I said, you're welcome to comment on anything that needs fixing.
Praise is also welcomed :)

** Here's some other guitar parts I heard in the song.
This one begins right after Brandon sings, "On a subway train before the dawn."
It's repeated twice and changes to the second part at, "Couldn't figure what got into me."
This progression continues in the same manner for the rest of the song.
I tried to tab it with timing in mind, but listen to the song to be exact, and let the notes ring.
