for the extruder you want to be around 400 steps /mm
this is normally achieved by using a 1.8 stepper with an 3:1 reduction, like in the bmg or titan.
for z 1.8degree steppers are fine. if you want finer resolution you can go with a different lead screw.
for example a 2mm lead screw with 1.8degree stepper gives 1600 steps / mm. more resolution that you normally need.
most people are fine with 8mm lead screw at 400 steps.
for x and y thats where you want 0.9 degree stepper motors. it does make a difference.
