2: Nolan chart:
http://en.wikipedia.org/wiki/Nolan_chart

Neither in model 1, nor in the Nolan chart (designed by a libertarian), are libertarians described as right-wing.
I think the FN wikipedia article refers to the classical 1 axis spectrum, which includes not really an economic definition.
I would describe the CCCP as a state capitalistic monopoly, as the state was the only entity able to accumulate resources and act in a economical way (economical not meaning using few resources in this context, just be an economical player). The PRC has a weird mixture of state capitalism and private enterpreneurship. It is the best example that a capitalistic economy does not necessarily need political freedom.
