1. Looks like you didn't install one (or more) of the archives, which
contain help pages, e.g. (from the readme):

rw1011h.zip                             text help
rw1011ch.zip                            compiled HTML help
rw1011w.zip                             HTML help files

[I suppose, you have installed the binary distribution for WinNT,
available at CRAN.]

Have a look into the "R for Windows FAQ, section 2.2".


2. Installing additional packages.
 a) It is possible to install additional packages using
install.packages().
 b) For windows there are binary releases of many packages available at
     http://cran.r-project.org/bin/windows/windows-NT/contrib/
    You might want to install those packages using the installer
rwinst.exe.

Have a look into the "R for Windows FAQ, section 3.1".
