I tweaked the code to be a little more readable and managable and added some documentation
Code:
/***************************************************
This is our GFX example for the Adafruit ILI9341 Breakout and Shield
----> http://www.adafruit.com/products/1651
Check out the links above for our tutorials and wiring diagrams
These displays use SPI to communicate, 4 or 5 pins are required to
interface (RST is optional)

/* parts used:
* 2.4" TFT display (display driver and settings will vary based upon display used)
3 pcs PIR sensor (HC-SR501) (this is a 2 or so dollar part)
1pcs ultrasonic distance sensor (HC-SR04) (this is also a cheap sensor)
1pcs piezo buzzer
1pcs 100ohm resistor
