Z-VISA APPLICATION INQUIRY

I have questions about the z application (form A) and information required. After looking at the instruction guide, I still found the instructions to certain questions too vague. Here are a list of text boxes I need assistance in answering:
Section 1:Personal Information
1.11) Local ID card number. Do I input my driver license number or social security number in this textbox?
1.17) Place of passport issue (city, province/state, country). Where do I find this information out?
Section 2:Travel information
2.2) Intended number of entries. I will work in China for 1 year contract. I will fly from Los Angeles to Shanghai, take a train to Hangzhou. I don't know if that information is helpful in deciding which option to choose. I also realize when I exchange the z-visa at police station in hangzhou, they will issue me multiple entries.
2.3) Date of your first entry (yyyy-mm-dd). Which date do I enter?
2.4) Your longest intended stay among all entries of your intended visits in China. My contract is for 1 year, if that's of any relevance.(Days textbox).
2.6) Who will pay for your cost of travelling & living during your stay in China? I am responsible for purchase of airline ticket, but reimbursed at end of the year long contract. My room & board costs are paid for by employer. How would I phrase all this?
2.7) Do you have medical insurance covering your visit in China? I do not have insurance. Is it required for entering China?

I appreciate any and all feedback to the mentioned questions.
