Last thing, for some reason in my head I tend to believe not to flash the car when it's hot and wait till cool down. Good practice or just some mumbo in my head?

Cold air intakes change how the air flows across the mass air flow (MAF) sensor. You can correct for this in the tune. Look up the MAF Scaling thread in the software tuning section of the forum. Without correction, the engine will probably still run decently as you have noticed, but it will produce less power, less reliably because the amount of air it thinks it is using will be wrong.
You can flash the car hot. I would do it all the time when making adjustments.
Note: Stage 2+ is for cars with catless headers iirc. You probably know that, just making sure.
