Do I file form I485, and my wife file I 130, and do I need a physical form I 94 to apply for a USA green card? Do I also need an I485-supplement 245?

You should read the instructions on the I-130 petition for alien relative which your wife will have to file for you and the I-485 adjustment of status application that you will fill out. The forms and instructions are all online at the USCIS website, USCIS.gov. Generally, you and your wife would file the forms concurrently. You can also file with forms I-131 for travel outside the US and I-765 for employment authorization. Your wife will also have to fill out the financial sponsorship form, form I-864. The I-485 supplement is not required in your case. A medical examination on form I-693 can be taken now or presented to USCIS at the time of interview. Good luck!
