Nearly every error you will encounter can be handled by a global exception error handler. An exception error handler can run any CF code. A request error handler is used as backup if something really bad happens, such as an error inside of the exception error handler. The request error handler is what needs the _javascript_ to post a hidden form to a CF page to send E-mail. But in practice 99% of your errors will be handled by the exception error handler, which can use the cfmail tag.
Below are the two lines I add to application.cfm:
<cferror type="EXCEPTION" template="exception.cfm" exception="ANY">
<cferror type="REQUEST" template="request.cfm" mailto="#request.adminEmail#">
ColdFusion also has a global 404 error handler that you set up in CFAdmin.
Good luck,
