An NFS mount is actually a really good idea in terms of conserving disk
space, although with disk costing less than $1/GB I suppose it doesn't
matter much anymore.

Any of several ways.  I'd suggest rsync or plain old cp from the NFS
mount.  There is also an extension of yum that can be used to mirror
repositories.  Basically, a repository is a directory branch containing
RPMS anywhere in its included paths down to 5 (? I'm remembering and
could be wrong) layers deep on which yum-arch is run.  E.g.

  cp -r /nfs/export/yum_repository_original /local/yum_repository
  yum-arch /local/yum_repository

will do it.  Then just add an appropriate repository section to your
local /etc/yum.conf to point to it.

Note that cp is not the best tool in the long run because it won't work
correctly twice and because it works much harder than it needs to.
rsync can be used to MIRROR the NFS repository regularly in a nightly
cron, gleaning only the changed rpm's.

Once again, though, I have to point out that for most purposes this is a
pointless exercise.  yum ALREADY automagically copies rpm's from the
remote/nfs repository to a local "repository" (cache directory) on
demand, it ALREADY gets 'em only if it needs 'em, it is ALREADY
optimally efficient in this regard, and finally, you have to do all this
on every system on which you want a local copy.  Adding a local mirror
makes sense only if it is for some other reason.

Adding an ADDITIONAL local repository for your OWN local rpm's DOES make
sense and is easy to do.  Just create a directory, drop your rpm's in
it, run yum-arch, add a repository section to yum.conf, and (if you want
its RPM's to take precedence over those found in the NFS/primary
repository) adjust your package update policy to suit.  The man pages
tell how.

See the yum article and almost finished yum HOWTO on:

I don't know what you mean by this.  What other packages?  What normal
ones?  There is a list of yum repositories posted on the yum site on
linux.duke.edu.  There are MANY rpm resources on rpmfind.  There are the
primary distro sites and their mirrors (many yummified at this point).
Is that what you are asking?
