The gleitpaste is amazing - its a lubricant paste that does not attract dust. It is used as brake pad slide lube on the caliper carrier, it is not applied to the pin area.
The best brakes for your car are made by Textar or Jurid - nothing else compares to those soft brake pads - for the pipes use OE PEX or Brembo rubber items - your car is a small engine variant and I doubt you will ever push these brakes to their limits.
