You're allowed one of jQuery/Prototype/Typekit
Entire package except the above library must be under 10kb - html, js, images, css, etc.
You're allowed to hook up with existing API's, eg flickr, google maps, but you're not allowed to load project-specific resources from them (eg uploading your header.jpg to flickr and loading it from there, or ajax requesting and eval()ing 100Kb of code).
11 days to go, I'm busy writing my entry as we speak!
I'm just using jsmin at the moment but I'll probably move over to using packer when I start nearing the limit. I'm on 5kb minified so far.
Another little trick I made use of instead of var foo = false; I used var foo = 0; - it's falsy so you can use it in the same way but you save 4 bytes.
Obviously these kind of optimisations aren't great for readability, but that's not the goal here.
