Anybody got CloudFront CDN and NoNumber CDN for Joomla working on ES site with updates showing as they are made?

I am sorry I wrote all of this in an old ticket because it seemed relevant but then I realized the ticket has been resolved so I should not have posted into it.
That previous ticket was #131423: CDN Questions For A Big Site
Now I am posting afresh here. Sorry for any inconvenience or confusion:
At https://www.starch-smart.com
I have set up Three CDN pulls using Amazon CloudFront for the CDNand the NoNumber CDN for Joomla.
These have organization where there was in NoNumber CDN for Joomla:
Images
Documents
Web Files (CSS and JS)
I am wondering how to set up my CDN Settings in System Preferences:
Enable CDN: Should I set this to Yes? Currently it is set at No.
CDN Url: I assume I leave this blank as I have three CDN urls all of which are CloudFront.net urls.
Client-side CDN: Should I be setting this to Yes? Currrently it is set at No.
I am also using the Amazon S3 option for my EasySocial Media files although I think that stopped working awhile back because there are a lot of images in my filesystem that have not somehow made it to the S3 bucket. But, that is a separate issue... :-)
How to configure the CDN settings in EasySocial as I asked above seeing as how I really have NoNumber CDN for Joomla handling that.
How to enable changes to Discussions or Social Posts of Blogs to be seen immediately on the service.
I am wondering if there is a way to set up my CloudFront so that the ismod (modification date) is checked each time a user comes to an HTML page.
Or, Do I need to enable some sort of url based versioning in my Joomla and at Amazons CloudFront.net?
Right now changes can't be made and seen immediately. I also have a bunch of boilerplate expires headers in the .htaccess file.
Thank you for anybody that knows how to make this work properly.
