Answer 1

Just bend and vibrato the 3. Don't play the 5.  I guess that's kind of the pitch that you bend up to from 3, but don't play it.   The tab on that part is wrong.  I just learned the riff for you.  I watched the video i the beginning and this is what the guitarist is doing.  Pretty simple. Don't let the tab confuse you. I'd never heard this before and learned it.  Just trust your ears.
