Here I am

Below I have attached my Unattend files. Thanks to Exhaler's (cheers mate) method of using two files for the routine,
it finally works as intended.
The AutoUnattend.xml finds itself in the root folder of the DVD. It contains:- The WindowsPE pass with language and locale settings, name and organisation, the product key (1st time), accepts the EULA and picks my Vista version "Home Premium" (32Bit).
- The Specialize pass skipping auto activation and checking for the appsroot.txt (using the well known command)
- The OOBESystem pass to enter Audit Mode (by using Reseal - Thanks for that one Hannubys, that was the winning line ! )
- The AuditSystem pass for Administrator AutoLogin
- The AuditUser pass holding the arguments for numerous applications with "silent" command line switches (Firefox, Thunderbird and TotalCommander (packed with Winrar, SFX Archive (silent mode) )
The Unattend.xml goes to \install and contains:- The OOBESystem pass to fill out user, system and country locales all again, the time zone, picks the network location, "ProtectYourPC" level, hides the EULA (again), fills in the serial (again, 2nd time) and creates a user "Sony" (with password).
- The Specialize pass for another time zone setting (maybe I can remove one of them, testing lateron)
The testing environment was virtual so far. I am using a vLited image (loads of stuff removed, SP1 slipstreamed aswell as all hotfixes and security updates "post" SP1. Also I included nForce chipset drivers) of Windows Vista SP1 x86 HomePremium. The installation was simulated in VirtualBox, a freeware VM by SUN. I got no errors so far and find myself on the logon screen with user "Sony" when everything is done. The initial login successfully loads up the desktop showing 3 links (Thunderbird, Firefox, TotalCommander), either of them working.
The only thing I actually have to do manually (on purpose) is to select the partition I want to install Vista onto, during the early setup. Exactly the way I always wanted to have this thing working.
Any feedback is much appreciated
