well using your current method the vars will of course will only be created and output once when application starts, so wont exist on any subsequent requests, which I do not think is what you want if they are JS variables you want them output on every page request in order for them to be available to JS, so you would need to do it onrequestStart or just by putting them in the actual html head.
Technically if there is no HEAD section then CF should not be trying to insert the content, so in your CFC's you need to make sure you have output disabled so that unnecessary content doesn't get added. You may also need to make use of <cfsetting enablecfoutputonly="true"> is some places as well.
