Ok, well this is my first ever tab, and I'm fairly confident about it.
For chords, I've tabbed a few of them as open, because that's how I prefer the sound, 
you can play them:

     C        
e|---3----    
B|---5----    
G|---5----    
D|---5----    
A|---3----    
E|--------    

  Dm
--5---|
--6---|
--7---|
--7---|
--5---|
------|

There's one other one I've seen on the net, and that's got the right idea. However it's 
the chords a bit wrong, so here it is:

e|---1----1-1-
B|-----1-----1
G|-2-----3----
D|-3-----3-3--
A|------------
E|------------

-|
-|
-|x2
-|
-|
-|

 Anything that uses those notes sounds good really. Or you can just play F and Fsus4.
