The attorneys will pick and chose the most important ones to prove their case. They will offer those exhibits up and ask for them to be admitted. If there is no objection from the other side the judge will allow that exhibit to be entered into evidence and then it becomes part of the official record.
Having the depositions done before the hearing will help the attorneys decide which exhibits will be used.
I am sure the attorneys will know those sm posts backwards and forwards, if during the hearing a witness lets slip out, the attorney can dig out another exhibit.
