Answer 1

I was able to resolve my issue once I worked with Microsoft Professional Services.  Here are the steps needed to deploy a Windows 8 Store app for anyone else looking for help on this.
Create your app package in Visual Studio

Create an app certificate using PowerShell as administrator, here is one way to do it.

Install the app on the device

Ensure Device has the correct GP settings

Install the application on the device
    Refer to Sideload the app for user section
    https://technet.microsoft.com/en-us/windows/jj874388.aspx
* If you run your app now you should get an error, this is because you have not installed a Sideloading Key
And the missing piece of the puzzle What is a Sideload key and how can I get one?
* Documentation on this is confusing so here is what I needed to know and found out
    Sideload key is a product key that is needed to be added to the device so that it can use Windows 8 apps that are not from the Store
    It is not a requirement to have the machine joined to the domain or have Windows Enterprise installed on it. In my case my target was a Windows 8.0 Pro tablet.
    You do not need Windows 8.1 to use sideloading it will work on Windows 8.0 as well
    You can purchase a key from a Third Party Distributor but you will need to know what to ask for
    Ask for a Windows 8 Sideloading Key, Sometimes referred to as a Windows 8 Embedded Sideloading product key
    They cost about $100.00 a pop but they sell them as a Volume License so the minimum you can by is 5.
    However in my case it turned out that my company had an Enterprise Sideloading License, I just needed to know who to ask and what to ask for.
    Once you get your xxxxx-xxxxx- Slideloading key from the distributor here are the steps to installing it on the device (Section 2 Step 3)

Once I installed that my application worked.
