OK, here's the numbers as far as I can tell...
Front bumper cover - $434.64 - 57704ag13
Fog Lamp assy N/S/F - $371.22 - 84501fe240
Fog Lamp assy O/S/F - $371.22 - 84501fe250
There are a tonne of clips etc but I reckon thos parts will get you started. My front bumper and fog lights were completely destroyed so this may be the COMPLETE fog light assembly but it appears to be the only mention... the only things mentioned are lower skirts but I can't see that would be the black plastic bit in the spec B bar.
remember the 3.0 bar takes a different lower STi lip to the GT and 2.5.
My guess is your foam bar support would be the same as the bars seem to be identical above the fog light section. If you need me to take some pics of the bar for comparison let me know.
EDIT: as an after thought, dump the foggies all together and run cold air induction from DS one
