File I-485 and other supporting documents with INS, for yourself and family within USA.
At this time you can also file for EAD ( Employment Authorization Document) and AP ( Advance Parol or Travel Document) , once you file for 485, you will be required to do fingerprinting.
In this case Step 2 and 3 can go parallel, known as concurrent filing, however 485 can't be approved without approval of I40.

Note: The overall process is time consuming, as involves formalities and lot of paper work. It is granted against per year Quota/per country/per category. Another constraint is that a person applying for a green card needs to stick with the company, through which his/her green card is getting processed, till he gets his Green card. Otherwise he loses the process, and needs to apply for a fresh application from the beginning.
