Passwords, install, & Drivers questions

Hopefully someone can help me out here with Passwords, install, & Drivers questions...

1- in the system summary xml file that is created the administrator password is in clear type.  anyway of fixing       that.  

Can I delete the system summary xml files that are created?

2- First time I used Image assist I believe it uninstalled itself.  I thought it was not anywhere in my image, but cannot be certain.  This second time using image assist I see the shortcut on all users, as well as my administrator profile.

3- when using the drive pack files, i am not exactly sure how to accomplish this.  Do i create a folder in my image before capture or is there another way of doing this?

Thanks for the help!
