It is hard for PP to go to the rim when the refs are letting them play, because he relies on foul calls. He also needs to dribble less (Salmons has the same problem). They need more pick and rolls to get the Pierce-Gordon matchup, and Pierce can take his favorite jumper all day on him. This would work best if the person Gordan is defending is a good jumpshooter, like House or Ray.
I don't care for the Rondo picks since the switch is easier for the Bulls since they aren't worried about Pierce hitting Rondo for a quick jumper. If House or Ray set the pick, they have to switch quick so that the pickers don't get free for an open 3.
The other problem with the Rondo picks is that Rondo usually has Hinrich or Rose defending him, both of whom give Pierce more trouble than Gordon.
The Pierce jumper from the top of the key over a small guard is a very effective shot for him.
