And The good ending was great but Nooj shot them so is Paine dead? or do you find out in the Den of Woe?

The way i understand it... Tidus was living Shuyins life... the fayth were dreaming the past and tidus came out of the farplane and lived with yuna in X. Don't tell me if theres more to it and its in the perfect ending. but am i off base?
