Someone else will have the number to call.
But I can help a little with the process of making requests. First of all, make your requests as few as possible. The more requests you make, the more likely they are to conflict with each other, essentially cancelling them out. It sounds to me like simply requesting the Jazz building would be very appropriate and probably fairly easy for ASMU to grant.
I'd go ahead and make the request ASAP. It won't put you ahead of people who check in earlier in the day and have the same request, but at least you'll know you've done your part already as far as making the request. They'll just keep the request in their system all the way until check-in date.
Some people have mentioned in the past that you should call again with the same request later and/or fax the same thing to the resort. That's a waste of time. You only need to make the request once, make sure the person you talk to understands it and enters it into the system, and the request will be in the system when you check in.
Keep in mind that these are requests, not guarantees in any way. Rooms are not blocked off from people who check in earlier than you the day you arrive. If people check in before you that day and request, even at check-in, the same building and it fills up, then they won't be able to meet your request. But if the building is still available when you check in, they'd try to put you in that building before any others.
