i also e-mailed the venue asking about how many VIPs were sold, how early they get let in, and what the line-up situation would be (if there was going to be one line for GA and another line for GA VIP) and the response I got was this:
"We haven't been given any specific information regarding the VIP will
call yet, and may not know until much closer to the show exactly how they are going to want us to handle that. Your best bet would be to give a call maybe a couple of weeks before."

they didn't give me an answer regarding how many Silver VIPs were sold, but hopefully we'll know the answer closer to the event date for anyone who is worried about that(:
