What's next?

Hey all,
I have recently gotten up to speed on grasshopper thanks to attending the ACADIA workshop in Chicago this year and I am hungry to progress further. Would someone please explain the pros and cons to VB, C#, and rhinoscript. I am trying to decide where to focus my energy. Which one should I learn next. Are there ways to learn these languages outside of the Rhino seminars. I live in Oklahoma which could not be farther from Seattle or Miami, where most of the Rhino clinics take place. I am hoping one of these languages might be common to other industries so I might find some classes closer to Oklahoma.

Thanks,
Stan
