I'm almost positive this is right. For the first verse, I just play the top string, then also play the second and third in the second verse. I play all strings for the choruses and all or most for the other parts. Also, if you can play barre chords. I would do an E shape on the third fret instead of G, and and Em shape on the fifth fret instead of Am, but only during the chorus. It really is the same thing, but it sounds a little different.
