Yes they are! I did not expect to find the Perl modules under the parrot directory tree. Sorry!
As for the docs, Rakudo\docs (from the .msi) contains the cheetsheet and UsingPerl6-draft.pdf, whereas rakudo-star-2010.07\rakudo\docs (from the tar.gz file) contains a different set of documents, including many pod files. This includes running.pod which you referred to in a previous post.
