As to your final question, to quote my freshmen year English professor, "Anything is hard if you do it well." The course I had in mind was relatively new, and as such its contents were in flux. The projects and lecture material were under constant revision. If the professors for the course I TAed had had the TA responsibilities as well, they would have had time for little else but the course.
