I can not offer any VIP access however having looked into this in some detail for a previous launch, you may find the following useful.
The Kennedy Space Center provides access to view the Shuttle Launch from within the complex. There are various positions to view a launch from, there is a charge for this and a limited number of places. The nearer the launch the more costly the tickets and the less available.
The Tickets are typically put on sale 4-6 weeks prior to the launch and go within seconds. To obtain one you need to be pressing the refresh button on the browser constantly at the time they release the tickets (this is known in advance). Decide PRIOR to the release of the tickets which one you want (as any hesitation could cost you the place), complete the process as quickly as possible. Note even though you may add the ticket to your basket, this does not confirm it until you have completed the process. Despite adding the ticket to your basket, you can get to the CC part only to be told all the tickets are gone. You could always watch the sale of the tickets for STS 133 which is scheduled for the 1st Nov. so tickets should be on sale middle of Sep.
The tickets are for a particular launch, so if the date moves, then your ticket remains valid for the re scheduled date (unless you have already entered the Launch center)
Things may have changed, but I doubt it.
There is plenty of info on the net regarding watching a launch, there is even the Kennedy web site
Orlando Florida Vacation Destination - Kennedy Space Center which contains lots of useful info on watching a launch.
