Hi, I am new with this engine also, and I had the same kind of questions that you have right now. I will recomend you the two tutorial that are at the download page about c-script and WED. Out of all the tutorials that I have found those two are the best for those who are starting. Learn how to work with WED first, then learn how to make c-scripts, then learn how to create models and terrains in MED. I have not found any tutorial for MED yet so I can't really tell you if is hard to learn or not. To write the c-script language is very easy but you will get a lot of errors at first. Don't worry about errors just bring them here to the forums and experts wil help you. Wed is not hard to learn to work with either. Of course that to become an expert you will have more problems but just to learn the basics is easy.
