If he is ineligible to practice, then he is defrauding you. You should contact bar grievence counsel to see if he can be disbarred for handling your case while suspended. If not then bar counsel should take on the grievence for the failure to bill you properly. If you sue or instigate a grievence against your attorney and it is a viable grievence and not frivolous, the court will give you some time to get a new lawyer. I know you indicated you are out of money, but you should have a lawyer who has your best interest at heart and who you trust. It seems the present attorney will not have you in mind if he is angry that he is not paid.
Finally the court usually will give you a fair amount of time to get a new lawyer and then give the lawyer time to get up on the facts and law of your case. You should ask for at least 2 months to find the right guy. Make sure he either flat fee bills you or he sends monthly bills out the door, before you give him any money up front. Demand that if you are being billed hourly that your funds be segregated from his funds until they are used and a bill with time installments has been sent to you
