LUA Coding tutorials?

[Eagle]

I'm trying to learn how to LUA code because I want to make a few entities. I've been on the http://wiki.garrysmod.com/ website for awhile and it helps with basics and understanding certain Hooks, Libraries, Classes, etc. But there are still things I'm not certain on. If anyone has any other resources such as videos, LUA files, or links for learning lua or any that helped you to learn lua; I would much appreciate it.
