Firstly, with regard to the time of the hearing. Most cases are typically listed as either '10am' or 'not before 2pm' but that doesn't really mean a great deal. I know of a magistrate who recently complained that a case scheduled as a 'whole day' case was listed as one of 43 cases to be heard in that court on the same day, with the vast majority of them listed as '10am'.
Similarly, I know a pub licensee who (in the days when the courts, rather than councils, issued licences) was required to attend court at 10am to apply for an extension. His application was heard at just after 7pm.
Even the court officials only have the haziest of ideas of when a case will actually be heard.
There's nothing anyone can do before tomorrow. In theory you, or your solicitor, could phone the CPS but, since the relevant CPS solicitor/barrister will be at the court anyway, there would seem to be little point. Your solicitor (or you) could then approach the CPS lawyer to ask if the relevant information had been received, and to confirm that it would be brought before the court. If not, you could ask that an adjournment be sought, to enable the court to receive the relevant documents.
