Confirming Correct Discs/Pads/Wear Sensors '15 X250 XF 3.0DS

[WJ9]

I am going to replace the front and rear discs and pads on my 2015 X250 XF 3.0D S - it has 355mm discs on the front as I believe all facelift (2012 - 2015) X250 3.0D S models had. Before going ahead and ordering, I'd greatly appreciate it if someone could confirm the discs, pads and sensors below are correct for the car.

Can I also confirm I will only need 2 pad wear sensors in total? (One for the front and one for the rear) Is the front pad sensor different given the discs are bigger than the rear?

Am I right in assuming I need to buy the pads with the piston clip?

What do Autodoc mean when they describe the pads as "without accessories?"

Front Discs: BREMBO COATED DISC LINE 09.B556.11 Brake Disc :

Rear Discs: BREMBO COATED DISC LINE 09.B312.11 Brake Disc :

Front Brake Pads: BREMBO P 36 027 Brake pad set:
 

Rear Brake Pads: BREMBO P 59 042X Brake pad set:
 

Front Pad Sensors: BREMBO A 00 460 Brake pad wear sensor:
 

Rear Pad Sensors: BREMBO A 00 461 Brake pad wear sensor :
 

Many thanks in advance.
