There is lots of jQuery material available for all on us on Internet or world wide web to learn jQuery. But the best way to learn any technology is to try your own hands on it. There are couple of good free jQuery development and debugger tools available on internet.
- Tools for Firefox
- Tools for Internet Explorer
- Tools for Safari
- Develop Menu (Available in Preferences menu item -> Advance Tab)
- Web Inspector
- Tools for Google Chrome
You can also test your code online on jsbin.
Feel free to contact me for any help related to jQuery. I will gladly help you.
