I just started Learning Lua as well (just for making plugins) and it is fairly easy, i found this -
http://www.lua.org/pil/index.html - that you can use to get a decent foundation on the language. If you already know how to program it is a super easy language to learn, if not i am sure it will still be fairly easy for anyone. but yea, that is a great place to start then you can learn more from reading other peoples code, and reading the api from Turbine. -
