white papers for sharepoint content types?

we create a lot of custom content types in sharepoint 2010 and have some unknown behavior. Sometimes we delete a content type, but we can't create a new one with the same display name. We only use the sharepoint gui to create the content types (no visual studio etc).

Is there a white paper for handling sharepoint content types? Which modificati开发者_开发问答ons of existing content types are supported by microsoft?

thanks :-)
