My standard advice is to dive in. Applying for jobs is what gives you the best information about what do you need to get a job. Analyze job offers, see what's in demand; try to get interviews and you'll get a feel of what do you need to prepare for interviews.
Having some courses on your resume of course can help, and esp. having played with the course labs gives you some practical experience that can be useful in an interview, but to break into a new job you'll need to apply for a lot of positions, and probably be told "no" a few times.
