I would consider if focusing learning CS or fundamentals is the right approach. What is the plan when he gets out? I'm not sure there's a lot of beginner CS or C jobs around without credentials. Is he going to try and go to school afterward and is that actually feasible? Otherwise I would suggest combining CS with more applied programming with smaller scope (like a web stack), developer methodologies (designing, methodology, testing) or design (interaction, interfaces, experience). Those would be things that he could more easily be practice as he gets out, aren't as focused on credentials and would more likely land him some sort of job.
