Forgot to add: make sure the coil pack connections are good. Press the flat top of the plugs down hard to make sure they're seated properly. I did this when the pack and leads were out of the car, then another press by feel once they were installed into the car.
I checked the security cam and calculated that all up it took me about 90 mins, from getting out the ramps at the start to closing the bonnet at the end. Others could probably do it faster, but it was my first time, and I wasn't in any rush.
