FYI:... I bought snapring pliers to ensure I didn't break the clips, but I ended up with pliers that didn't spread far enough. Oh well...
What I ended up doing was using pliers as stated above, just grab the top of the clip and wiggle side to side as you pull up. If the tabs catch it too much, use the screwdriver to pull it back while you pull up with the pliers again. I didn't break any of my clips using this method... once you get the first one off, the others are cake.
Good luck...
