ha - in the workshop there is a scoreboard on the wall.
"Bikes with Hayes brakes - good or bad to work on?"
As of yesterday, there are zero marks in the "good" column.
Although as you've observed, you have to prise the pads apart. Take the pads out and use a plastic tyre lever to push the pistons back. They are self-adjusting pistons so the idea is, you push them all the way back, then squeeze the lever (while the brake is mounted on the rotor), and they retract just the right amount. If they're not retracting far enough, you may not be pushing them back far enough in the first place.
I'm sure an expert will turn up soon enough, I'm just procrastinating here really...
