China Visa Application in Osaka for Malaysian

I hold a Malaysia Passport. Currently, residing and working in Japan. I have a work permit. Coming December 2016, my friend and I plan to visit China (Tibet and Shanghai). I would like to know how can i apply for an entry permit?
1) Where can i get the application form? Which is the correct form to be filled?
2) Where can i pay the application fees? Direct the Osaka Consulate?
3) Do i need to make an appointment prior to my visits to the consulate? How to make a reservations?
4) What is the require documents? I read some Q&A above, so do i need to bring transportation arrangement and hotel booking record? Meaning i need to purchase all my travel plan tickets and hotel booking completed before i apply?
Thank you
