There is also node.js camp next week (12/14) in San Francisco.
We also have a pretty decent collection of coverage from older Node.js talks - 8 videos, 15 slide decks, 3 podcasts etc - linked from the right hand column of that page.
Joyent is doing a great job putting it together and I'm excited to speak.
NodeConf is a slightly larger community event that is more like a typical conference and less like a tutorial. It's also going to be a gathering point for the node.js community to come together from around the world.
