1) It tries to follow the books and it does a decent job but it can't put everything into the series so it does cut and change some, but not in critical areas.
2) Yes it does follow the chronology for the most part but sometimes it will move things around so that Dany has something to do or Arya. But nothing negatively reflects the story.
3) OH HELL YES! Best TV on television. Great acting. Fabulous scenery and directing. The books come to life with joy.
