How do I sign over full child custody rights of our son to my ex?

The child has a right of support regardless of where he lives.

Generally, a parent cannot give up their parental rights to their own child unless an adoption has or will take place. There must be a willing and able parent ready to assume the legal responsibility. If there is a child support order in place it could be petitioned to be modified. Normally in a proceeding for modification of any child support or maintenance judgment, the court, in determining whether or not a substantial change in circumstances has occurred, shall consider all financial resources of both parties, including the extent to which the reasonable expenses of either party are, or should be, shared by a spouse or other person with whom he or she cohabits, and the earning capacity of a party who is not employed.

What difference does living abroad have to the need of your children for food and clothing and recreation and education and health care?

The parent in the USA can still have child support obligations to pay child support for a child that lives in another country. You cannot give up your parental rights to avoid your child support obligations. Your not paying child support can only be accomplished by an agreement with the other parent, but not in all cases.
