Do an install, set the yum.conf to keep RPMs after use, and upgrade. Now 
link all the rpm files in /var/cache/yum to a single directory and run 
createrepo. You now have a repo of just the stuff you actually found useful.

One the next system, do the install, update from "your" repo, then set 
the "save RPM" flag and update against the usual official repos. Move 
any RPMs you use to the local repo. This will result in pulling anything 
you need only one, and having only things you actually do need. Best of 
all, you can use scripts to do this either automatically or by typing a 
single command, as makes sense for you.

There's a command to prune the local repo to only the latest version of 
things, sorry I don't remember it off the top of my head.
