From what I am aware and of my personal experience on changing my controller, the white backed unit is the newer style controller.
As for the glow plugs, I would recommend going directly to Mercedes for the parts as they are not that expensive and you are sure to get the correct glowplug.
Personally I use Castrol red rubber grease on the sliding pins and Mintex Ceretec on the areas of the caliper housing where the pads slide.
This time around I did the pads myself. The previous owner had them done by Mercedes however the pins were near seized and rusted as they clearly had not...

I can't say that I am impressed with this particular dealership.
To add to it all the...
