First, don't worry about new frameworks or languages right away. You can stick with PHP/mySQL on the back end to start.

Learn all the updates to CSS first, to understand how pages are structured without tables. That will help you to move on to jQuery, which will in turn help you understand how JavaScript is used nowadays to work with the page. Once you are that far, you can pursue node.js to get up to speed on server-side JS.

After that, you should be as caught up as you need to be, and will better be able to evaluate all the other frameworks and languages out there, and set your own direction.
