The course requirements are very similar as they would be for a theory degree, including orchestration and conducting. As for composition lessons, you can expect a variety of approaches. Most teachers will have you do various exercises (exploring different styles and instrumental combinations.) You can also expect to study electronic music (sound design, sound engineering, sequencing, etc...)
You'll also be required to have lessons in a secondary area; I would assume piano in your case.
After graduation, you pretty much make it on your own in whatever way you can.
