btw. Welcome to the forum, from one newb to another
As rks suggests the rattling is not a great concern so long as you monitor the pad pins for wear. If they get worn too thin, they could snap under high stopping force.
As to the oil being "black" I am rebuilding a Diamo Velux 250cc engine (Helix clone) and the oil was extremely black as yours, but the only internal damage was from poor service techniques.
The coolant you mention is something I am going to change. The water pump impeller and cover had excessive corrosion and he was using the green coolant. I may replace it with the gold coolant spec'd by Audi as it protects really great. Also the clamps are the screw band clamp, I will replace them with "spring steel" band clamps that continuously tighten themselves.
the differential in this one is built too tight and requires too much effort to hand rotate, thinking of increasing the gasket thickness to about 0.030" to open it up just a little and reduce friction.
