It seems that the procedure to replace the cam chain wear pads are the same steps that are used to replaced the IMS: mentioned here numerous times "lock the crank at TDC, lock the cams (with the special tool), then remove the variocam actuators and replace the wear pads" perhaps with the upgraded LN billet machined ones.

Question: Is the tool to lock the cams the only special tool required? Is this a straight forward job that can be accomplished by a DIY with standard tools?

I was refering to the CAM chain wear pads for the 97-02 Box engines seen here: here:

this was changed in the 02 996 3.6 & 03 986 3.2 & later so no worries for you there.

Below is the oem IMS to crank chain tensioner paddle you are refering to at the far right side of the picture. You can see the round wear pad that contacts the tensioner plunger & you can inspect for wear by removing the Tensioner.
