I am not sure if I am able to distribute any of these files legally as a package so I will just write down the cookbook to create that package for yourself. You can also just leave me an email address for a faster solution.
1. Download Apple iTunes package for Windows XP: http://www.apple.com/itunes/download/
2. Use 7zip (http://www.7-zip.org/download.html) to extract the iTunesSetup.exe into a folder
3. Use 7zip again to AppleMobileDeviceSupport.msi inside that new folder
4. Copy the needed driver files into a new folder of you choice (e.g. c:\AppleMobileDeviceDriver):
usbaapl.cat
usbaapl.inf
usbaapl.sys
usbaaplrc.dll
5. Use DPInst (http://msdn.microsoft.com/en-us/library/windows/hardware/ff544842(v=vs.85).aspx) the Driver Package Installer from Microsoft to install the "Apple Mobile Device USB driver" inside the usbaapl.inf file.
Command line: (/C to see logging output, /Q to display no dialog boxes, /PATH X to point to the driver files in path X, /SA if you do not want to create an entry for the driver under Add/Remove Programs)
dpinst.exe /Q /PATH c:\AppleMobileDeviceDriver
Et voilá .. you got a clean install of the Apple device driver with removal option in Programs without unnecessary services, files or even iTunes. And a working image unload with the WIA Camera and Scanner interface in Windows XP.
Alternatively you can also install the AppleApplicationSupport.msi and AppleMobileDeviceSupport.msi from step 2 or use GBlings suggestion to involve another tool to install the drivers for you plus some Apple Device service as already mentioned before if you like crud on your PCs ;-]
