Mapping the pins was quite simple. You just look at the printed legends on the pcb. e.g. DB5 (LCD_D5) goes to 13, LCD_D1 goes to 9, ...
Your photo does not seem to show a LCD_RST. I guess that the pcb connects it to the AVR_RESET pin.
Anyway, #4 shows that you got LCD_ID_readreg working. You have a genuine ILI9327.
If you followed the instructions in #3 (or in mcufriend_how_to.txt) , the MCUFRIEND_kbv library would just work.
