i use a setting between 20-35 for jerk settings. and 1 on the z axis setting. this is about right for my machine. any faster print quality suffers, and i have parts start to loosen up. you do want this as high as possible because prints will take less time. there are a lot of short moves in a print job. this setting effects the short moves. acceleration kicks in afterwards.
I think default settings are around 15. currently I have set my latest printer a prusa to 25 for x,y and 1 for z.

For Tantillus I have the Acceleration set to 10000 for E and the Jerk set to 100 because of the need for a 5.5mm retract on the Bowden cable and we want it instantaneous. This may not work for most printers since on a bowden machine the filament springiness is enough to accelerate the extruder backwards really fast and prevent skipped steps while retracting.
