Gayle,
The volumes consist of documents from the trial that support the brief. Those are usually submitted, if not always submitted. The brief itself contained more words than allowed by the court rules, hence being designated "oversized." The scheduled actions for April 2 are reminders to follow up on whatever the court ordered the WTS regarding their oversized brief and to follow up on the pro hac vice request to allow representation by one of the WTS' New York lawyers.
