How do you connect BeagleBone black to a LCD screen with a 40-pin TFT Friend?

I am a student in computer science and I am currently working on a project to create a gameboy from scratch with only a Beaglebone Black REV C, a 40 pin TFT-friend that I bought here, and a 5'' TFT screen bought on buydisplay.com/default/5-tft-lcd-display-module-wvga-800x480-high-resolution-for-mp4-gps. Because of the small amount of information available, we probably did something wrong and our beaglebone black short circuited and refuses to tu on. We bought a new one and are looking to prevent that from happening.

1. Which pins of the beaglebone black are connected to which of the TFT friend? You can see our current TFT pinout on Beaglebone Black to TFT connection. Before our beaglebone black fried itself and refused to tu on, when we tued it on, the screen lighted up and you could see a white background and the backlight tued on.
2. How do we display pixels or images on the screen? As the description of the TFT says: "There are no tutorials on how to use this TFT-friend", we do not know if we need to write our own driver for this screen or if there's drivers out there ready to use with this TFT-friend?
3. Are we missing a hardware piece? Our teacher wants us to use only these 3 elements mentioned in the first paragraph, but are we perhaps missing one important element that might help us display images on the screen?

Can someone help us?
