Delete fields after removing last field instance

Sweet Module, I;m Doing some pre-beta testing and wanted to share the errors, that I am Getting, and a few suggestions, But first here is my setup:

General server information:
Operating system Linux
PERL version 5.8.7
PHP version 4.4.1
MySQL version 4.1.14-standard-log
Host Bluehost

error when creating a new feild type:

warning: Missing argument 3 for nodereference_field_settings() in /home/animalso/public_html/cvs/modules/cck/nodereference.module on line 45.

{Getting the following error when re-editing its feild type:

* warning: Missing argument 3 for nodereference_field_settings() in /home/animalso/public_html/cvs/modules/cck/nodereference.module on line 45.

* warning: Invalid argument supplied for foreach() in /home/animalso/public_html/cvs/modules/cck/content.module on line 787.

{After deleating a feild the feild still shows as option in feild choices,
Suggestion: I think it would be better if we could completly deleat them.

{Suggestions: would be nice if if we did not have to re-edit all pages if creating new feilds for there type. Getting the following error until re-editing

* warning: Invalid argument supplied for foreach() in /home/animalso/public_html/cvs/modules/cck/nodereference.module on line 93.
