RDF* is an extension of RDF that aims to make modeling certain kinds of n-ary relations easier. As the working group note you mention shows, there are other ways to represent such relations in RDF without needing an extension, but they all have certain drawbacks. RDF* hopes to overcome some of those drawbacks.

Yes. The approaches for modeling n-ary relations shown in that note are still as valid today as they were in 2006. It's just that RDF* gives you another option, that (hopefully, in some cases) will make things easier.
