The grand mother has no rights.. and do not listen to anyone who threatens to take your child away. With what you have said, a change of custody will never happen. In the future, tape all conversations with them (make sure you let them know first) and record any threats.
Is there any court ordered visitation in place today ?. If he is just taking about general rights of a father then HE will have to petition the court to get visitation. At this point to agree to only short supervised visitation and no overnight stays or leaving the county. A judge would probably agree to this since the child and biodad are strangers.
If he is serious about the relationship with the child, he will continue and eventually be able to remove those conditions. However, from what you have said, he would probably get tried of it and go away.
If these people threaten you.. do not talk to them.. tell them once that you will not deal with them directly and all communications should be through an attorney.
As for child support.. are you trying to enforce it or just not bother ??.. if he has not paid and you can live without it.. do so until he starts legal proceedings. THEN go after him..

SMILE - Start Making It Livable for Everyone
Divorce is a process over which children have no control. Children should not be its victims.
When parents are under stress, it is harder to be in touch with their children's pain and anguish.
It takes time, effort, and planning on the part of the parents to be able to provide for the children's needs.
In the crisis of divorce, parents may put their children on hold while they attend to adult problems first.
Sometimes separating/divorced parents find that their roles and expectations are undefined and cloudy.
If handled properly, divorce need not be devastating for children.
