Not to come off rude, but you should really seek a consultation from an attorney. If they think you have a case maybe they might do it on some type of contingency payment. You should ask multiple attorneys. What you are asking is probably too complex to answer in this type of arena.
Check with your local legal aid office to see if there may be free or low cost lawyer representation available to you. If you can't get a lawyer to help, you will just have to do the best that you can to understand the rules and options and comply with them. Make your filings as clear as you can; make sure you serve copies of the filings on all the entities that you are required to give copies to; and make sure to file something before each deadline, even if it is only to ask for more time.
