If you entered with a B1/B2 visa and overstayed, you are out of status. Some call this a “B1/B2 overstay”, although technically that is not a status. If your USC spouse is filing an I-130 petition for you, you do not need your father's I-130 unless it was filed prior to April 31, 2001 and you are seeking to be grandfathered under section 245(i) of the Immigration and Nationality Act, but why would you need to?
Take a look at the instructions for filling out the I-485 and follow them carefully. Make sure you include all the evidence requested. I have listed the link below. Good luck and congratulations on your upcoming nuptials!
