X1 visa application questions

Hi!
Its the first time i have to fill in an application form and on some questions i am uncertain of what to write.

1.2 Name in chinese - I am not chinese. I do have a chinese name but its just something I made up not like official name or anything. Should i write that name?
1.16 Education - I have a bachelor degree and i am going to china for my master degree. Which one should i check Postgraduate or College (since I havent obtained masters or even started it yet i guess college is appropriate isn't it)?
2.2 Intended number of entries - is "one entry valid for 3 months" the right option?
2.6 Itinerary in China - i haven't planned on traveling in china yet, i guess i will stay only in nanjing, is that information sufficient?
2.7 Who will pay for the travel and stay? i have a full scholarship, can i just write that + myself?
2.8 Information of inviter in China - do i have to provide the university's info?
All the other questions do not apply to me should i fill in all with NA or should i leave them blank?

Also i have few other questions. It is required to have a flight ticket reservation for the application, but should it be round trip or one way is enough and does it have to be already bought or only booked will be enough?
Do i have to print the form on 4 separate pages or on 2 two sided?
Do i have to stick the photo or not :D
All the required documents have to have photocopies, does it matter if they are colored or should they be black and white?

I know thats a lot of questions but i am stuck.
thanks
