Definitely MySQL, and go advanced in PHP and Javascript and perhaps a tad more CSS than just basic (although CSS is quite basic on its own, it's still very interesting to continue to learn it a bit).

Oh I forgot about SQL, I am ok at SQL, quite handy actually.
I'm not sure if MySQL and SQL are the same thing...
MySQL is a database service, SQL is a programming language nearly universal to all databases. There is a little variation between databases and the way they interpret SQL, but not a whole lot.
Although there's the Microsoft SQL Server, a database service, that could be called SQL for short if you wanted to...but that's just picking at details.
And, yeah, go advanced with PHP at least. It's useful. JavaScript is definitely something worth looking into farther as well, but I would learn more PHP first.
