This is off of "White Flag" and took me some time to figure out but I finally got it.
finger picking could be slightly different from his but its hard to tell.

standard tuning   (This means slide /)
Basically, he is picking the chords that I have written above the tabs.

verse picking...

Well that's basically all, I hope its easy to understand..by the way you can pick in 
different ways and it will still sound right.
