Creating a local repo is basically the effect of running revisor.  If 
you keep a copy of the disc or installation tree that revisor builds, 
you can use it later to avoid downloading packages that haven't changed. 
  If you don't want to rebuild the installer, you can also use the 
reuseinstaller plugin to copy the installer from the image you compose 
as well.

Yep.

Not normally.  You'd have to gather the repodata from all of the 
repositories in the revisor configuration file, build a list of all of 
the packages available, and then remove those that appear in your image.

Yes.  It will use what your kickstart file states is required.  It may 
also pull in a small number of additional packages which are required to 
build the anaconda installer.  Older versions of revisor do this even if 
you are using the reuseinstaller plugin.
