For me there's nothing else I really use consistently on a daily or weekly basis. It just depends on what I'm preaching, teaching, or focusing on. I refer to commentaries based on what book I'm preaching on, other texts based on what's going on in the life of our congregation or areas of personal I need to work on. There are some works I try to make a point of revisiting regularly: The Institutes, The Art of Prophesying, The Reformed Pastor are among them, but certainly not on a weekly basis.
