You should consult the summary http://cran.r-project.org/bin/windows/contrib/checkSummaryWin.html
to answer such questions. These are not part of the install of R -- you must have chosen to install some packages which depend on them. As to whether you need them -- that depends if you need the packages that depend on them. You are wrong about xgobi: it is on the CRAN extras site and a default repositories setup will find it. However, it is an interface to XGobi, and that is pretty much obsolete in favour of GGobi (and rggobi is its R interface). Package gtkDevice has been withdrawn. It should be possible to build package RGrace for Windows -- it only depends on packages RGtk2 and cairoDevice these days, and I've just done so. (Earlier versions were a different story.) However, it fails its checks as it incorrectly uses "UTF8" (instead of "UTF-8") for an encoding name. (So Cc:ing the maintainer.)
