HAML and SASS are nice to have, but nowhere near necessary to get a job - you can learn them pretty quickly on the spot. I would recommend that you start learning Javascript and jQuery. They're both enjoyable and will seriously boost your front-end development skills, while getting you familiar with programming.

In the meantime, if you find a job that looks just slightly out of your reach, try applying anyway, and mention during your interview that you're learning Javascript in your spare time and really want the opportunity to develop your skills. If you have the code you're working/learning on available somewhere (either a zip file, GitHub, or SourceForge), you'll still be ahead of many candidates who say they have more experience.
