I'd be very grateful if you took those things on! Personally, I suspect that one good way for this kind of thing is for it to be written by a newcomer and then fact-checked by the veterans...the former group are more familiar with the feeling of not knowing what the hell is going in. I think the cookbook is a good format, "problem" "solution" (each of those a one or two liner) "discussion", "reference", and then "example" -- ideally ready to compile code, with the relevant bits highlighted in red, and all the usual boilerplate in black -- that keeps us honest in our code, and lets the n00bs have the small thrill of assembling code and seeing the results.
