The video isn't available here, but you can cut the project in to smaller chunks (which may be individually complex) such as make a test breadboard of only the tft display and get the logo working then integrate that code and hardware (mostly I/O ports) in to the other sections of the project. Doing that lets you deal with one problem at a time such as getting the display running with text output to debug the interfacing, then change to graphics mode (once you know the hardware is working) to get the logo to the display either via the library or a bitmap and then evaluate whether the result is bright enough for what you need. With a display panel you may not want to have metal in front of it as there will be viewing angle issues probably. I'd mount the screen to the front panel. If you cut the logo out of the front panel your better and easier solution would likely be a piece of plexiglass illuminated by leds. You may have to try both and see which works better.
