I think newer Javascript books are beginning to add or expand sections on client-side uses and node.js in particular. Two that I know have sections are Test-Driven JavaScript Development[1] and JavaScript: The Definitive Guide, Sixth Ed[2]. The TDD chapter on node is probably already out of date in some respects, the Definitive Guide no doubt will soon be out of date, and both are smaller/smallish. There is also Tom Hughes-Croucher's Up and Running with Node.js[3], which is in progress and available through O'Reilly's open feedback system.
At the moment, blog posts and online tutorials seem to be the way to go, though you have to be careful there too. Node seems to be moving very, very fast, so things will likely require a medium amount of tinkering, even if they were written two weeks ago.
I think what I'd just like is a JS primer that goes through certain features in the language that could be useful for server-side things, including Node. Especially closures.
