Lets see if I understand this. The messages I am getting are abnormal. In order to fix them I need to erase the disk (not zero it, not archive and install) and reinstall Jaguar from scratch (my disk does not say it is an upgrade but does not give me the archive and install option). At this point I have no easy way of backing up my entire drive so this will have to wait until I buy an external HD or CDRW. I did find a way to install 10.2.4, rebuild the directory structure and optimize the hard drive. None of this got rid of my problems. Thanks for the advice.
