Most applications you can simply use the Recommended Software Set (especially when just getting started)! If you get to the point that you need more customization/software, you can always install more software on the controller.
You can also get a feel for how to communicate with your modules using the built-in LabVIEW examples (Open LabVIEW, go to Help >> Find Examples. In the Example Finder that opens, navigate to Hardware Input and Output >> CompactRIO >> Module Specific IO. In that directory, you should find many examples for your modules.)
