I'll check what resistors I have in the morning, but if I don't have a 100ohm resistor, would it be better to go slightly higher or lower? and I did have a potentiometer if I can't find anything
Be careful not to go too low. Clamp the FETs and watch the current draw while doing this.
If you have a pot, you can insert that in series with the 820 ohm resistor.

The factory 820ohm resistor, about 1.61A of current draw, but when clamped they seem to heat up less than I remember, barely detectable temperature change in 1min of running.
Proceeding free air, With a potentiometer set to ~100ohm in series with the R175 820ohm resistor, current draw is 1.59A and heating is about the same as before
waveform looks like this:
source to gate (negative on source)

From what you've posted, I think it's OK. Test thoroughly and make notes in case you get another one in for repair.
And should keep the 100ohm resistor right? Won't be able to do full power tests until it goes back in the car in an unknown amount of time, will report back later with how it does.
There was no significant change so the resistor probably make no difference. I'd probably go back with the original 820 ohm.
