1) Solder mask is automatically added to all PCBs. You can enable the solder mask layer in the Layer Settings but the best way to view the solder mask is by generating the Gerbers and using gerbv or the EasyEDA online Gerber Viewer. You must check your PCB this way anyway before submission. 2) Yes.

Thanks for your answer, I have one more question: I want to remove the name of some parts on the TopSilkLayer, for example for some diodes I don't want that D1 etc. is written beneath every diode. Is this possible?

Great, thank you! I searched the forum before, but did not find this one...
