I already did 400 miles and front has lost again 1/4". He'll then make an final alignment, end of september, just before my first track day with the car.
At the moment, because of the lowering, front has around -1° of camber and rear has much more. Front toe has been corrected, as you suggest, to the original factory values. Again, because on the lowering, rear has more toe in, but this has not been modified, since the car seems to be well balanced with that setup, and it saves labor (anyway the car will lower again and everything will have to be reviewed).
-2° on front seems huge to me, especially if you stay with factory toe out. It will certainly reduce understeer, but it will reduce a lot tires life, no?
Thank you for the suggestion on caster, will try that 
BTW, bilstein PSS make a huge difference to the standard suspensions. I am very happy with them.
Camber plates do not seem to be homologated in switzerland for street use, but I'm waiting confirmation. I saw some using M3 lower arms, do they allow more camber even if we don't go for camber plates? Are we speaking of the E90/E92 M3 arms?

Your mechanic is correct about the new springs settling --- good man.
-2* is fine for street use with occasional 'spirited' driving. Maybe I drive more spirited than others, but from my experience -2 is fine on tire wear for the street.
Yes, the E90/92 M arms allow for a bit more camber. Talk to Harold @ HP Autowerks, he sells them and knows all about them. IIRC, they add about .5* of negative camber, but double-check that with Harold.
Good luck man, keep us updated
