You may be confusing some aspects of physical custody with legal custody -- and they are different, as explained here. To answer your specific question, no, an award of sole legal will not stop child support. It is unclear whether your situation is "good enough" for sole legal (such decisions are very fact-intensive). Other observations: You can get an order for one-party (you) ability to obtain and renew passports. Child support is reviewable on changed circumstances, or every 3 years, or to correct mistakes/fraud in an FDF, at any time. There are things that can be done to collect arrearages, and the D.A., while free, is notoriously slow, inefficient, and does not properly compute interest and penalties. See here and here.
You may want to consider consulting with a family law specialist who can advise you on all aspects of collecctions, and possibly modifying the existing custody and support orders.
