2A is pretty simple, although I'm not sure if I'm forming the chords just
how they do.  Either way the notes are right, play them however you want.

D:------------------------------------------------------------|
A:---XX5-XX3--XX3--XX2----------------------------------------|
E:---XX5-XX3--XX4--XX3---(etc.)-------------------------------|
2B is played over top of the first two chords of 2A, it creates that cool
erie feeling.

I am totally unsure about 5, it does something like this, they might even
be using some weird effect along with it.  This is the riff after all the
vocals are done and 3 is played along with it.
