As you can Tell I don't understand this lookup and shiftout code. Any Ideas?

Did you wire the 7-segment LCD display to the AY0438 chip? If they came together as you said earlier, do you have the datasheet for this part? More than likely, the wiring that mark_s used in his program is different than the way you are wiring it. You need to know how the segment pins in the AY0438 are connected to the segments in the LCD display. You need the part datasheet.
