Ok I Know how to change one of the elements that you talked about. Here's how: Open LogonStudio and select the skin you want to change. click "edit"
In the edit window click "logon" and scroll down to "Edit Theme.ini"

This will open a notepad window where you can edit the text

The line you are looking for is "6=" in the [strings] section. The default is "Type your password" - you can change it to say whatever you like! There are other things you can change here as well, so just have fun. when you are finished close window and Windows will ask if you want to save. Hit yes and you are finished!
As far as "loading your personal settings" I think this is part of your OS (windows) and cannot be changed (at least I don't know how)
Hope this helps you
