It looks like you have posted a number of questions here that all boil down to not really knowing how Labview and the provided WPILib VIs work. I highly recommend you forget about the specifics for a minute and try to get a grasp on the basics.
I would recommend you go to this website:

Watch videos 1-4 under "2011 FRC Steps to Robot Success". Watch video 5 if you get far enough to work on autonomous mode.
