A great resource (at least it used to be) for credit and other consumer disputes is http://www.debtorboards.com/

This was started by one of the refugees from the artofcredit forum.

Another resource is the National Consumer Law Center (NCLC) at http://www.nclc.org/

Their publications on FCRA, FDCPA laws and pleadings are considered superb textbooks for the aspiring pro se litigant.
