Yes J8C1 is the header then each point is .1 .2 .3 etc. just follow trace. Removing the resistor will not improve boot times but any resistance in the cpu_rst line will affect or stop the reset hack. That's why the cpu line needs to be as short as possible or a shielded cable. The original point is on the cpu side of the resistor, so the resistor can stay. Remember to bridge that gap with a little blob of solder if u do remove it. U will need the resistor back on if u return to stock console in the future. Edit: Careful with too much heat around pll_bypass (A). That can easily blow the cpu protection diode, rendering the cpu dead.
