I think that HKS thing is a waste of hard earned money. You could've done the entire thing yourself for much cheaper. Also, grounding the int and front iron are kind of a waste. The rear holds the coolant sensor for the gauge, so that is kinda nice to re-ground.
The housings are key for good spark so I would definately ground those, as well the ECU points, housings, waterpump housing, TPS, pressure sensor, and maybe the MAF. Everything should be common and leading to a GOOD chassis ground or to the battery. When I did mine I started with an 8 gauge grounded by the ECU that spiderwebbed out with CRIMPS (NOT solder) to hit all the key points.
