To do the intro for Even Rats as easy as possible, heres what you should do.
1)Barre the G B and high E strings at the second fret with your index finger, creating a D7 chord
2)Stretch your middle finger to the third fret on the low E string
3) Put your ring finger on the 3rd fret of the B string, creating a D/G chord
4) To hammer-on the 4th fret* on the G string, use your pinky
