Hi matto,
Nope, no special tools are needed. The Magura RT series brakes (RT stands for Road Team, Magura's MT stands for Mountain Team) install like normal brakes. They also use the same bleeding tools and hydraulic parts as all Magura's rim brakes. A few hex keys, one Torx T25 (same as used on disc brake rotors) and the basic syringe and oil that comes with the rim brake service kit are all you need.
And yes, instructions are included. :-)
Speaking personally, since ours is a mountain bike free household, I was blown away at how simple set up and service are. This is quite an improvement over many of the so-called "superbikes" and one of the reasons we chose the theme "Simply Faster" for the P5, emphasizing not only that it's faster, but also not as complicated to work on as many competing bike models can be.
Cheers,
