Well first off, the noise suppressor should be at the end of the signal chain, to suppress the inevitable noise from all that processing/bypassing (cuz I assume those Boss boxes aren't true bypass), and the tuner at the beginning, just for the sake of getting the cleanest tone to it. So basically, I'd put the tuner at the beginning, followed by the Maxon, and the NS at the end...I guess the rest in between is up to taste (but it's rack Multi FX in the loop all the way for me!)
