also, 1M would be fine... difference if you used a 470k resistor is you would get a slightly lowered gain from the first stage, and slightly less resistor noise.
sorry correction... just looked at the scheme and saw that this resistor is after the coupling cap... yeah, i'd say 1M looks pretty sus to me too.

also, i just looked at the f/back loop, and maybe the 100ohm resistor is what it was meant to be, becuase the shunt resistor is only 150ohm... still this is pretty unusual and i don't see where the designer is coming from if it was intended, and is not just a mistake... still, this will give an unusualy high amount of feedback...
