I apologize that this happened to you. I see that we do use a pretty common naming scheme, so I'll try to get that updated in the next version to prevent this circumstance.
It uses the css file names /css/styles.css and css/admin.css, so you would have to be careful to not use those file names.
The script file names are probably at least a little more obscure.
For a complete list of files you can go to:
%appdata%/Adobe/Dreamweaver [your version]/en_us/shared/webassist/PowerCMS/CMS/
That is the folder that is copied into your site.
