Velocity and Accel settings are different from machine to machine so unless someone has exactly the same setup no real numbers can be given.
Steps per unit can be calculated, what you need for that is the steps per rev of the motor which in your case is 200. The micro steps of the drive which I dont know for the Hobby CNC stuff. The pitch of the ballscrew and finally if there is any gearing between motor and ballscrew.
