To disable autoupdate add the following registry key:

[HKEY_LOCAL_MACHINE\SOFTWARE\Apple Computer, Inc.\iTunes\Parental Controls\Default]

"AdminFlags"=dword:01000101

thanks for your answers

Create a 32bit DWORD value called "adminflags" (without quotes) under "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apple Computer, Inc.\iTunes\Parental Controls\Default". Give the DWORD a value of 256 to disable automatic updates. From there you can export that registry key and import it after installing your itunes package with the command regedit /s "MyRegKey.reg"

All of the decimal values for various settings can be found here: http://support.apple.com/kb/HT2102
For multiple changes you will input the sum of the desired values.
