The bumps as you refer to them are called "vias". They do go through the board DO NOT DRILL THEM (you will most likely destroy the connection from one side of the board to the other), you can see them in the pictures you posted in the OP. In fact it looks like they go to the pins 12, 11 and 10 as referenced in the first picture, can't you just solder to there? Or you can even solder to the pins on the connector (7JN1, pins 12, 11 and 10).
