Copy profile in Windows 7 is done via sysprep. Basically you install the OS, press Ctrl + Shift + F3 at the Windows Welcome screen to enter Audit mode (you can also run c:\windows\system32\sysprep\sysprep.exe /audit /reboot). You can then customize this account the way you like it. After that you need to run a sysprep and capture from MDT with CopyProfile set to true in the answer file. Sorry but I am not sure how to answer the rest of your question.

Do you receive an error during the uninstall? I have seen this come up where the service for Bonjour will not delete properly, but you can manually delete it ("Sc delete "Bonjour Service"") and then rerun the uninstaller.
