Well, I had my meeting with the department head and everything seems to be handled.
Due to instructor availability, both of the Art History classes that I wanted to take this fall were canceled. However, he compiled for me a list of classes that I could take from this fall's offerings that could be made to fulfill the credits that I need. A class in one of the required categories that I need to graduate will not be offered in the two semesters before my preferred graduation date, so they will allow me to substitute another class.
In addition, one "class" he suggested is a museum internship. I had never even considered this option before, but I am thinking about it now. I'll let you know.
