Suing Collection Agencies?

I have read, and am semi-well-versed, on the FCRA and the FDCPA...I have sent letters via UPS Second Day Air and the 30-day time limit has passed, and want to have these items removed from credit report and these agencies to pay for their laziness...however, two obstacles I need help with:

1) Credit Bureaus can mark your file with a 'red flag' and call your claims frivolous if you dispute too many at once (not my fault the information ended up there, but I did do a mass dispute with all 3)

2) What jurisdiction do I file suit? My own, or the jurisdiction of the C.A.?

Any help would be great.
