In general, we usually recommend using a motor driver that has a continuous current rating greater than the stall current of your motor. From the motor specifications I found on this website, it seems like you should be able run two of those motors from each channel on the VNH5019.
The VNH5019 operates in drive-coast mode, so its output is generally not very linear. If you want to get a very linear output then some kind of feedback is probably needed.
The VNH5019 shield does not regulate the voltage it supplies to the Arduino, the jumper simply connects the reverse protected VIN voltage to the Arduino's Vin.
If you are having trouble using your VNH5019 shield, you could post pictures and more technical details about the issue on our forum.
I tested our Spring RC and Parallax continuous rotation servos over an update frequency range of 50Hz to 200Hz to see how they were affected. The only change in performance I noticed was that at slow speeds the servo moved a little bit faster with higher frequencies. However, the change was not a significant jump in performance, and changing the frequency had no effect on the top speed of the servos.
