Well, you can always get a free evaluation copy of LabVIEW. It runs for a month (I think).
Most of code is compatible between regular and student version. (See the
FAQ). There are probably some limitations with respect to to use of external code and non-NI hardware.
I think the best option would be to contact your friendly local NI rep. He/She will be able to answer all your questions in detail. They're all great!
