I am Thai student studying in Nagoya. I want to ask the required document for applying visa at Chinese consulate in Nagoya

I am Thai student studying in Nagoya.
I am just curious about the required document for applying visa.
I will go to China next month but I reserved air ticket with the agent by internet.
And they won't sent it to me until around a week before flying.

So is it OK to apply visa without the document of air ticket?

And one other question, I plan to live with my Thai friend studying in Beijing.
So, can I get visa easily if I write to the consulte that I will live with my friend?
(I think it's difficult for her to send some confirmation of overnightstay to me)
Or I should find some hotel for living overnight just 1 day for giving this information to the consulte?

Lastly, can I go to Consulate at Nagoya by myself without prior contact?

Thank you for all of your useful answers,
