Is it really that advanced? Looking at some similar projects mine seems kind of low end on the difficulty scale.
Depends who you are comparing with. With experts: it is very simple. With me: it is out of my ability. I just use Arduino for fun, because my teacher introduced the Arduino Starter Kit to us. I'm okay at programming. What have you done with Arduino before this? Compared to my classmates and teacher with Arduino, I'm the "expert". 
I'll try to answer you're questions when I have time. I'm very busy right now.
