For question 2, dev.new (in more recent versions) will start a new instance of the default device (which are the ones listed below), but in a cross-platform way (so you don't need to remember all 3, and code will work on the other platforms).
A link to dev.new should probably be included in the "see also" section of the help page for windows/x11/quartz, but I don't know if it is important enough for a formal bug report. -- Gregory (Greg) L.
