Hello! First let me give you some information about my situation.

This year I have been granted a Chinese Government Scholarships (full coverage) for a master degree in China. It starts September 2017 till July 2019. During these 2 years I intend to stay in China. I have come across various information about the documents needed for visa application.
I have the following:
1. Valid passport
2. Copy of the data page of the passport
3. Medical examination record
4. Copy of bachelor degree diploma and its translation and legalisation.
5.Filled (almost) V2013 form.
6. Passport size photos.

So, I want to ask if I need a flight ticket reservation and if yes should it be one way or round trip. Since I do not expect to leave China for the period of my studies i doubt i can book a ticket for 2019.
Also I need some help with filling the form.
2.5 Longest intended stay in China among all entries - 720 days (is that OK?)
2.6 Itinerary in China (it asks for detailed address)- what should I write here?
2.7 Who will pay for your travel and expenses during your stay in China? - as I said I am gonna be a scholarship student but i don't know how to properly fill the information.

IMPORTANT: I am still waiting for my admission letter to arrive and i have no idea whats that JW201 form, where can i get one, should it be provided to me together with the admission letter?

I appreciate any help and thank you everybody in advance!
