I'd avoid high speed power tools. low speed and keep it cool so you dont mess with the temper. Id also add an 800 grit round in there, as for how high to go, your looking at 8K to 12K. How low you can go, its a lot better to take your time and go slower, its always easier to take less metal off each pass than to try and put metal back on. Might be able to get some 325 grit wet/dry.
