The first step I would take, in your situation is to discuss your bill with the lawyer and see if she can reduce your bill for the requests that were made more than once and any time involved in those requests. To me, that seems the place where you would have the best chance of a deduction. Whether she will grant you one, of course, is up to your lawyer.
As far as your lawyer's choice to sit silently, that will likely be considered her tactics, for which whatever fee she charged during the time she sat there would be appropriate. She was still there and your dislike in how she handled the situation comes down to a personality disagreement more than a fee issue. Sometimes, lawyers and clients disagree as to how something was (or should be) handled.
Review your fee agreement as to postage and copies. Such things are normally charged in a family law case, and the explanation as to why you were sent copies would be acceptable to me.
In the end, if you believe that the fees were inappropriate, would be to file a fee dispute. I would start by checking to see if the county in which your lawyer is located has a bar association which provides a fee arbitration option. But keep in mind, a fee dispute is normally only successful when the lawyer overcharged in an obvious and extreme fashion.
