Does this program have three basic categories that are present in the same place all the time? Pictures, Music, Videos/Movies? When he taps an icon to look at his favorite TV shows will it then present a grid of pictures, each representing the shows that are on the WD TV Live Hub? And when he is done playing a file will the program send him back to the main menu or to where he left off?
Yes and No … there’s a Free version (non-pro) if you wish, to “try before you buy”

Also, can this software be used on a tablet with a wired GIgabit connection (or USB 2.0) back to the WD TV Live Hub as a control/feed wire? I don’t like having wi-fi on in his house. If not is there an equally easy to use program for a Windows 8.1 64-bit tablet that will do the same?
If you have a Tablet with a wired Gigabit Connection … try the Free version to see if it will work
