E-Slayer conversion please help with some questions

Ok so im converting my slayer to vxl brushless I will be running a maxamps 3s lipo, I would like to know if there is a way to get rid of the mechanical brakes, and use the motor brake I also want to keep it 2 speed. Also what gearing would you suggest. I would also like to get rid of the clutch bell and run it direct with a longer pinion. Thanks
