Well, some of us that run our own instances try to document the setup and running of SN. I have a list started here: http://url.jpope.org/j6 that may help you all out. Most everything on your wiki page will be doable. So be sure to have whoever will be doing the majority of the SN config to not hesitate on asking us questions. ;)
Federation and groups are partially broken to be honest. You’ll only receive notices from those you are subbed to, or those on your instance are subbed to.
