Once you have things pretty much working then you probably need to stop using stepconf and start using a text editor to tweak the HAL file directly. HAL has more flexibility than any GUI Wizard can ever cover without becoming more complicated and impenetrable than text-editing.
As for what the numbers mean, they are very similar to the stepconf numbers, except that the step length and step space are not controlled by the step-generator directly in most configs, instead the "reset" function is used to control the step pulse length, and the base thread frequency ensures adequate step space. The "reset" function is a simple function that is called some time after parport-write and just checks that it has been at least reset-time nanoseconds since the parport step pins were set high and if so, sets them low. If not, it waits then resets. There is a slight performance advantage to be gained from putting other base-thread functions in the "gap" between parport-write and parport-reset so that the system is working rather than waiting.
