When I did mine the old ones were as follows (and replaced the same way with new parts). The retaining pin went through the caliper, through one pad, through the spring, through the other pad and through the other side of the caliper.
As I understand it the springs are to stop the pad rattling.
Oh, and if you fit EBC Greenstuff then expect them to drag for the first few miles until they bed in - I was a little worried until I consulted a friend who uses them on more conventional fast road stuff, apparently this is normal! Mine stopped dragging after about twenty miles or so and have been perfectly well behaved ever since.
