Can someone help me with few questions I have please?

1 - Is first post on Page 1 still the most recent/accurate information for renewal?
2- Do I have to send the forms in a specific order? I was told to do so for my last renewal but I forgot the order.
3- I will be shipping it to Chicago P.O. Box 5757 via UPS express. Can I send it with signature confirmation?
4- How many pictures do I need to send?
5- If a whole page is not applicable to me, do I put N/A for each box or just leave it blank as it is?

Thank you,
