If you're going down the Wiki route I'd highly recommend Atlassian's Confluence. It's the easiest to setup and most user friendly (for non-techy types) Wiki that I've come across to date.
Don't know about setting it up -- didn't do that part, but the admin page has waaayy too many options for my taste.
But when running it is an awesome wiki. We are in the process of adopting it, and using it in combination with gliffy diagramming plugin is a killer feature.
Being able to work on a page and drop a diagram in all without leaving the browser or worry about uploading files means we can actually keep the diagrams up to date with the documentation.
