Run the surge protector on the back or underside of your desk, then do all your cable management there. That way, the only cables that go above your desk are going directly to your devices and not leaving a lot of length all over your desktop.

For wires that ABSOLUTELY have to go on the desk itself, I absolutely love these rubber clips, especially for my headphone cables, which I'm constantly removing from the clips. They tend to last significantly longer than plastic clips in my experience, with the downside of not holding the wires quite as securely when they are mounted upside down.
