Back to the op question. I replaced the pads on the cam tensioners, fairly easy with the engine out. I did not replace the others as it seemed that I would have to dig a lot deeper to get at it/them.
I did not have the special tool ( essentially a bolt with a left hand thread) to compress the variocam tensioner/actuator thingie although I actually bought a die to make it myself, like all the other tools I used. I posted some pix on those home-made varieties.
