Stop looking around for ways to get better. Open your editor and make something you think is cool. Rinse, lather, repeat.
read (and understand) the "learning javascript with object graphs" series http://www.google.com/search?q=site%3Ahowtonode.org+Learning...
use node.js for the backend of your apps to come (start with https://www.duostack.com/ or for a quick hack http://jsapp.us/ )
do not use w3school ressources (they are wrong in critical cases) see http://w3fools.com/
and the most critical tip if you really want to get serious about javascript: learn other programming languages as well, then revisit javascript. one language can never be enough. take the learnings from other languages and apply them to javascript.
oh yeah and: do not seek cross browser compatibility. it's frustrating. (after you are good it will work cross browser anyway (excluding IE)).
