My question involves adoption law for the State of: PA

I had a son out of wedlock in MI. The bio father is on the birth certificate. Over the course of a few years things went from bad to worse. Bio father has since gotten his parenting time suspended in 2011. My family and I (husband and other children) have moved to PA. My sons domicile has been changed to PA. Since the suspension of parenting time, which was granted after bio dad got a drunk driving with my son in the car, he has had NO contact. No calls, letters, nothing. The requirements for filing to have his parenting time reinstated was alcohol and drug counseling and clean urine samples and breathalyzers. He has made no attempt in two years to complete these. He pays some child support but is always behind. Our ultimate goal is to have all rights terminated and my husband adopt my son. My questions are these;

1. Can I apply for a name change in PA before our child custody case has been changed to PA ( The friend of court in mi still has authority over the custody issues but unsure about name changes)

2. What are the chances of proving abandonment and moving forward with step parent adoption once the case has been transferred to the state of PA? If there has been no contact at all and no attempts to correct the suspension of parenting time does the small amount of child support I receive enough to prevent a termination?
