If they're the originals I'd recommend changing the master cylinder seals too.
Also lubricate the lever pivot and the back of the piston where the lever bears on it with a small amount of the thickest grease you have available. That often makes a huge difference to the feel of the brake and may make it easier for the pads to retract that little bit further.
Having said that, the pads will always rub slightly. So long as they're not dragging hard enough to make the disc warm you needn't worry.
