Jake,
Glad to hear you're intestered in Creo! You can absolutely import them into the student edition of 2.0. When you click on either Open or Assemble (if you're creating an assembly) you have the option to change the file Type that you are a looking at (see below). If you set it to Inventor Parts or Inventor Assemblies you should be able to import them.
This will be much improved when Unit technologies comes to Creo 3.0, so keep an eye out for it!
