Hello, daesummer. There're many websites about the bible and forums where you can ask questions, in english and chinese, and explanations on the biblical texts.
As I've learnt from school, the gospel according to John and the book of revelations are believed to be written by John the disciple.
The Old Testament is timed before the birth of Jesus Christ, and the New Testament is after his birth.
As for the biblical texts full of names, just skip them, before you fall asleep.
