Actually, there is an easy solution to your immediate problems -- and a more general one for the support problem.
First, with a relatively simple motion for a court order, you can cut out the requirement for spousal consent to passport issuance; if your attorney does not know how to do this, he or she can contact us. If you do not have an attorney, feel free to call.
On the support matters, you can directly enforce by wage assignment across state lines; if that is not working, the D.A. can intercept tax refunds -- and you should get the amount updated to account for increases, AND seek reduction of arrears to judment with penalties and interest. For details, see here and here.
