I am looking an app that will highlight on the home screen if the "Data Connection" setting is on
does such an app exist?

You might check out Data Connection Shortcut | Windows Phone Apps+Games Store (United States)

Also check this one out. I've been very pleased with it. You can pin Airplane Mode, Location, Cellular, Wi-Fi, and more to your start screen and when connected, the tile shows if the connection is on. Works great for me!

Quick Settings | Windows Phone Apps+Games Store (United States)

Both are great, but don't update the status on the live tiles.
with the app "Quick Settings" I need to open the app to update the tile

I use Cellular Live Tile. Keep in mind that the live tile can only be updated every 30 minutes due to OS limitations.

Using "Quick Settings", I have a tile on my home page showing showing the status of the cellular connection.
When I touch it, the cellular connection page opens.
Is it possible that when i move away from the cellular connection page, Quick Settings automatically opens and after a short period of time closes?
This should update the status on the live tiles
