There are any number of articles and blog posts out there that address some aspect of jQuery. Some are phenomenal; some are downright wrong. When you read an article about jQuery, be sure it's talking about the same version as you're using, and resist the urge to just copy and paste — take the time to understand the code in the article.
Here are some excellent resources to use during your jQuery learning. The most important of all is the jQuery source itself: it contains, in code form, complete documentation of the library. It is not a black box — your understanding of the library will grow exponentially if you spend some time visiting it now and again — and I highly recommend bookmarking it in your browser and referring to it often.
