It doesn't sound like you have mastered any one particular language. I would recommend pursuing one of the ones you have some experience in (Rails, PHP, or JavaScript) and making projects from scratch. Being able to build an entire application or utility from nothing and understanding all the parts is a great skill to have. I would not recommend learning any particular framework (web or otherwise) except as a tool to gain mastery of a language. Frameworks are scaffolding to allow you to use your understanding of a language to effectively build your idea into working models, they should not be treated as the be-all-end-all of a language. Limiting your learning to jQuery or Rails instead of trying to learn JavaScript or Ruby themselves will not get you the mastery you need to grow as a developer.
