Jquery is a library and javascript is the coding language. Basically Jquery makes it easier for you to do certain functions. INstead of writing 20 lines of javascript code to show/hide a div, you could use jquery and use one line instead. I'll advise you to learn jquery after you learn javascript because it will be easier for you to understand the concepts. If you're looking for good tutorials, check out w3schools. You should also get into the jquery IRC to get your questions answered.
