Customize calendar entry function for a specific meeting room

I am trying to modify the calendar entry form in the mail file to have additional fields only when a certain room is selected. In addition, when this room is selected, I need it to automatically change the start and end times on the reservation stored in the reservations database to block out the entire day, 7 a.m. to 7 p.m., instead of the timeslot the user selected. I also need it to automatically reserve the day prior to the start date, 7 a.m. to 7 p.m., and the day after the end date, 7 a.m. to 7 p.m., for IT setup and cleanup.

I am having trouble finding where in the calendar entry form or the reservation form to appropriately do what I'm trying to do. I've tried workarounds, but none of them are working the way I need them to. Do you have any ideas on how to go about this? We have a training room we want to allow reservations for, but the boss wants this all done through the users' calendars and wants the IT setup and cleanup reservations made automatically once the users' schedule their timeslots.

Is this even possible? I'm having trouble finding information that will help me. Any information you can offer will be greatly appreciated.
Probably the best way to work this is to set the room as a resource that "Only select list of people can book resource via auto-processing - all others require owner approval." Then the owner can book the additional days and approve the original request.

See the Technote #7003347.
