Verify that the following file exists on your MOSS server after you activate the RadEditor features: \Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\CONTROLTEMPLATES\RadEditorList.ascx. If the file is there but you still do not see the editor, try restarting the MOSS web application (do an iisreset).
If the file is not there even after you activate the features, you can copy it manually from the following folder: \Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\FEATURES\RadEditorFeature\. After you copy the file, restart the MOSS web application.
