One of the best sources for federal whistleblower information is whistleblowers.gov.  It provides detailed information about federal whistleblower laws including the text of the law; summary of the law; how to file a complaint under the law and deadlines relevant to the law.  An excellent chart showing  this information may be found here. 

Survey of Federal Whistlleblower and Anti-Retaliation Laws also provides a great resource for information.
