Breaking Dawn? The series.?

Ok so Breaking Dawn when its Jacobs point of view. Does he sleep with Bella? And what happens to Bella? Why does Rosalie care so much about Bella? When does Charlie find out about bella being pregnant? Does Edward and Bella still sleep together after chapter five and six? What does imprint mean? And when does Bella change into a vampire? Thank you if you answer the questions. Two of my friends have read the book but I can't talk to them at the moment and my sister has but she won't tell me anything.
