Getting started with jQuery - where do I go next?

Getting started with jQuery - where do I go next?

I'm new to jquery, and can write basic functions but I've hit a learning barrier. I'm eager to learn more, but I feel directionless and overwhelmed by jquery terminology. I wish to learn it properly and at my own pace, on a side note: my job frequently requests me to "debug JavaScript issues" or "expand on/add features to: third party API's".

I don't really know where to go, what to learn next... Can anyone give me some pointers?
