looks good so far
the SMD go upwards as you have done then the socket can only go one way as there is a pin/notch,
then when you build the upper board again smd upwards. Fill all the 060 holes that the board has with the pin strips, then use the red yellow picture (find the correct orientation by the 060 missing pins/notches, easier to assume the red/yellow picture shows the underside of the board ) and trim all the yellow red pins from the underside of the upper board. Then push together
