If there's any IL-2 guide to flying jets I know not of it: just stumbling along as I can

Not really. In general if you fly a jet that can flameout or catch fire you just have to be smooth with the throttle. Taking off with full power is easily possible, again just smooth throttle movement. It doesn't have to be snail slow. The fastest I'd power up is from 0 to 100 in around 2 - 3 seconds. Any faster than that and you risk a fire. The key to fighting is not really speed in general. People tend to relate jets to speed but fighting with jets is more about precision and getting the speed right. Most of the time flying 83% as low power is good or if you need more then go to 92%. Full power is rarely needed unless you need to chase someone. I wouldn't play around with the throttle over around 500kmh. Under that you can slowly power down to 0 etc but I'd say more than 3 seconds to go back down.
