I would highly recommend going through some of the tutorials there are for labview online.
I haven't used labview in FRC for the past few years, but I found these guides immensely helpful back when I was using it:
http://www.frcmastery.com/
The guy that narrates these is very knowledgeable and covers a large number of beginner and advanced topics quite well. It would be to your bennefit to go through these guides and understand some of the concepts.
It looks like NI has put up their
own set of instructions for 2013.
I quickly looked through, and a slight modification to
this guide would probably help you do what you were looking for (driving back and then turning).
[EDIT] On closer look the auto mode "tutorial" isn't much more than some screenshots and isn't much of a guide. I'd suggest watching
this video from frcmastery on the 2011 auto mode code. It should be helpful in understanding how to structure an auto mode to do what you want.[/EDIT]
If labview is something you're interested in learning more about, in preparation for future years, go through the guides linked above. Even the ones that don't sound like they will be relevant to something you need to know will likely teach you something new.
