Sorry for the delay in response. Sounds like others are also having a positive experience, but I thought I would still answer your original questions.
Sensor is at the output of HEX (technically at the input of the MLT where the wort returns to mash but the difference of 1.5 feet of hose). I would definitely support the notion of putting the sensor somewhere after the wort leaves the HLT coil. And yes, the sensor controls the HLT burner.
I have not step mashed but usually employ a mash out (so, like a step). Control can be very tight but certainly depends on how fast the recirculation flow rate is. That will be the important thing to notice on your specific brew system. A slower rate should help you have a closer range between mash temp and HLT water temp.
Some pictures are attached. Not the best but just wanted to quickly grab some off my phone. ImageUploadedByHome Brew1404409494.368903.jpgImageUploadedByHome Brew1404409522.574972.jpgImageUploadedByHome Brew1404409560.377728.jpgImageUploadedByHome Brew1404409581.562334.jpg
