You only have to understand one language, and that's c-script, which is the same in german and english. Just have a look at how it's made - basically it's just defining a material, create an effect using a fx-file (use one of one of the demos) and assigning this material to your model with an action.
If you want to have bump mapping on level textures, you may have a look at the bump mapping demo which can be found at acknex unlimited. (and this one is in english
)
