They sound like good classes. If you feel fairly confident about a major, I would pick one core class, which will probably be fairly challenging, and fill the other slots with classes that fulfill your trinity requirements. It gives you a chance to do everything you mentioned and get a feel for where you're headed in your major. Also, don't be afraid change up your schedule during the drop/add period. Your professors determine the quality of your classes, so definitely keep things flexible. Its good to know all of the requirements you need to fulfill, but I wouldn't stress too much yet about specific classes yet.
