The team358 website is a great source for isolated pieces of code to do specific jobs. It has helped me many times.
Three years ago, our C programmer left the team and we started from scratch learning LabView. I relied heavily on
http://www.frcmastery.com/. They have many tutorials on not just learning LabView, but they are specific to FRC. I just checked and they have not updated tutorials to this years game, but for learning labview in general, the 2010 and 2011 tutorials are still appropriate as the framework has not changed much.
You can also find general Labview tutorials at NI's website. Some that I have used in the past are

and don't be afraid to ask lots of questions!
