How do I link all the classes together so I only have to add one syllabus, grading, etc.
I believe what you're looking for is cross-listing a section in a course. Following this procedure will move other sections into your main section so all of the course materials can be managed from one course. This will of course put all of the students together into one course shell so make sure that the situations in which you're cross-listing are within keeping with your school's policies.
