Hi Tom,
Vray for Rhino is almost identical to Vray for Max. It uses the same types of vray lights, materials, sun/sky system, physical cameras, settings, etc....
There are a few things that aren't incorporated into VfR yet like vray proxies I believe and certain types of materials.
You can download the Rhino trial and the VfR trial as well to check it out. I think to teach Vray only it'll be the same if you just use Max, but not sure if they're expecting to also learn how to apply materials, set up lights, etc.. For that you'll have to be a little familiar with the Rhino interface, but it's not very hard to do.
I would recommend you look through the free PDF manual for VfR from ASGVIS website. It's a step by step manual, very thorough.
Let me know if you have any questions.
