Is it worth it? Yes. I make nearly $90k/yr working for a Fortune-500 entertainment company and I only have a two-year degree and a couple of professional certifications working as a code monkey.
I recommend learning Java, the MS .NET framework (once you can code in Java, C# is a breeze, they're basically the same just C# uses the .NET framework for its library) HTML5/CSS3 and Javascript (not the same thing as Java). Probably get at least familiar with SQL, too.
