I've gotten a number of emails from FIRST teams asking for more tutorials on how to get started with NI LabVIEW. We are developing some customized content to help you succeed in the 2009 FIRST Robotics Competition.
In the meantime, check out these engineering resources:
LabVIEW Guided Tour
Introduction to Graphical Programming
Tutorial: Get Started with LabVIEW
Tutorial:Customizing a Virtual Instrument
