I can't tell from your question whether the will was filed after your father's death, but based on my understanding of your question, you have options. You need an attorney to intervene on your behalf to advise the court what is going on and name a new personal representative to settle the estate. You have a right to see all of the documents and receive an accounting of everything in the estate.
I agree with Attorney David, that you need counsel and that you are entitled, as an interested party, to review the estate's records. That being said, there are assets that pass outside of the estate, such as joint tenancies, POD accounts, etc. You may not be entitled to that information.
