So this what I have. The grid actually works and all I really need to do now is add in all the Metadata and positioning of everything. I used <autoLayout>1 5</autoLayout> under imagegrid to specify how many columns I have as well as how many games are shown in the grid. Anyway, thanks again for the help, even though I ended up figuring it out for myself. At least I know that what I did matched your suggestion to a T.
Thanks all. I found the theme building youtube videos from RetroHursty. Super helpful. Ive made some modifications to an existing theme to make something I am happy with.
@gamehedpro You click on the Code button at the top of the repository and you can download the theme as a .zip file:

After you extract the archive, you can copy the theme's folder to \\retropie\configs\all\emulationstation\themes (create the themes folder if it doesn't exist) and then you can choose the theme from EmulationStation's menu.
