You can play the B/F# in a couple of different ways. This way is how it sounds like he
it in the song:
B/F#: 221xxx
But, if you feel like adding in a nice note (a bit tricky though), play it this way:
B/F#:2214xx
and use your pinky for the last note.

If neither of those suite you, you can always play it this way:
B/F#: 2244xx

Just make sure not to hit all those high notes, as the "proper way" to play the chord
be... at least not in the acoustic-guitar verses, because it's only the bass notes played
the song.

Lastly, in terms of ending the choruses with the E major to E minor switch, you can play
chord to the next, or, to sound more like the song, you can strum the individual notes
this:
E--------------------------------|
B----------0------------0--------|
G--------1---1--------0---0------|
D------2------------2------------|
A--------------------------------|
E--------------------------------|
