You've pretty much got it... On the sill panels (the bit you're pointing at) you put the scissor jack in between the two little cutout bits. There will be 4 of those, two on each side front and rear.
As for the other two, DON'T use the scissor jack to try and lift the car from the middle, they're not rated for that much weight. You'll want a hydraulic floor/trolley jack... But yes you've got the jacking points right.
