Have in mind that making mods ain't easy at all. If you expect you'll see a video and instantly learn everything about modding, that'll probably won't happen. Start with learning how to use the GECK and then learn how to use blender or 3ds max.
That being said, here are some of the best tutorials i've seen for advance modding.
