Apart from messy, it's quite confused, but I'll try to answer what seems to be the essence of your inquiry. You need to consult with qualified legal counsel. Most attorneys will provide free (but limited) initial consultations. I would take one or more up on that offer, and I would start with experienced criminal defense counsel. I have the impression that you have no attorney at this point so start talking with counsel before you worry about whether you need one or two attorneys.
My experience has been that it is usually to your advantage to have the same attorney handle all of your open cases. The attorney will be aware of the facts of each case and can represent to the court the status of the various cases, which may impact the disposition on a given case. If the cases are in the same court, the attorney may be able to negotiate a "bundle" type disposition. It is important that you consult with a local criminal attorney to assist you in these matters. Good luck.

Its always best to schedule a consult with a qualified attorney to review your situation and offer advice if it is worth pursuing a law suit. I would agree with the previous post to have the same attorney discuss your options.
