Random questions from first year programmer

[Wawa]

Hey everyone!
As you can tell, it's my first year programming and I have no idea what to do. My team has no programming mentor so I'm just relying on CD. I was hoping someone could answer some of my questions since I finally got LabVIEW up and running.

1. What's the difference between Arcade Drive Robot and Arcade Robot with Arm?
2. Which one should I choose to start the code?
3. Can you explain how to program an Arcade Drive so that someone with no programming experience can understand?

I'll be putting up more questions as I go along, so please bear with me.
Thanks!
