Apologies, only just seen this and I suspect that your event was the weekend just been, so much of this is now out of date....
However, for others searching...
A media pass at Mallory only gets you 2 feet closer to the action most places and the ability to get into the spine of the narrow section.
Main corners to cover Gerards, Devil's Elbow, Shaw's hairpin, the Esses. Biggest braking zone is the uphill into Shaws hairpin and people will out break each other in order to overtake. A good exit, a good run through Devil's Elbow and people will try and pass on the main straight into Gerards.
