Something else to attend to:

What is the relationship between the VA disability compensation program and the Agent Orange Veteran Payment Program?

There is no connection. The Agent Orange Veteran Payment Program was established as a result of settlement of a class action lawsuit brought by Vietnam veterans and their families against the manufacturers of Agent Orange. The application forms, claims processing, eligibility criteria, etc., of these two programs are completely different. For additional information about the class action lawsuit and benefits from its settlement, see Agent Orange Brief, A2, call toll-free 1-800-225-4712, and/or write to the Agent Orange Veteran Payment Program, P.O. Box 110, Hartford, Connecticut 06104.

From here.

UPDATE: No, no. That program closed in 1997.
