  I've tracked the noise to the rear passenger side, behind the wheel.
There seems to be some
  electrical device there but I have no idea what it is (I have no
manual or anything).. Any clue ?

This is the fuel pump and the noise it makes comes free of chanrge.
Mine does the same. Bit more noisy when cold.

Then You also wrote:
- - When cold, the engine has a "tac-tac-tac-tac-tac" sound (valves ?
lifters?) ...
   any idea what I can do about this?

Just change the oil and filter first to see if it will stop.
