Uninstall Parallels App Doesn't Work

I'm trying to rid my MacBook Pro of Parallels 3.0. I ran the "Uninstall Parallels Desktop" application and it said it completed, but the Parallels folder is still in my Applications folder and a bunch of files remain in the StartupItems and Documents. Trying to run it again, it tells me that my comptuer doesn't have Parallels installed.

Do I have to manually delete everything? What about all the crap it installed onto windows?
