I am sure that WM UK could help. Please excuse my stupidity and give me a little while to work out exactly who is on WM UK before I suggest more.
There are no official members yet since it's still in the planning stage. We have a list of interested people at http://meta.wikimedia.org/wiki/Wikimedia_UK_v2.0
Clearly, any kind of contacts with technical or schools journalists would be good: we will send out review copies (probably on USB drives). WMF are supporting the launch with quotes etc.
Liaising with the press is certainly something WM UK could do.
