If you are attending our first semester of Foundations you will need the Wacom before the oils. I would suggest having the tablet at the beginning of the semester and the oils will not be needed until the third month.
I teach the media class, I will suggest that you can get by without an easel. A large drawing board with clips to hold paper would work for most of what we are doing, eventually you will want to get an easel or drawing horse. The tripod you will need for the Digital Photography class for Artist, plus it is a tool that you will use throughout the program and your career.
I hope this helps!
