Please note that I only suggested to short the pins very briefly for testing purposes.
Your camera does it every time, when it fires the flash. I thought since you measured the trigger voltage, you'd be fine doing this quick test.
Another way of testing compatibility with standard radio triggers is to put the flash on a camera of a different make. If it fires, it will work with radio triggers. This is really the same test as the shortening test since the camera of the other make does nothing else but short the pins.
BTW, the triggers you pointed to use a special 23A 12V mini battery for the transmitter. If I were you, I'd get triggers that use standard AAA (or AA) batteries. I'd also make sure they can handle up to 300V trigger voltage as this will allow you to use other flashes on them as well.

You cannot control the flash's contribution to the exposure by varying shutter speed. The latter only controls the ambient light's contribution.
Your only options of controlling the flash's contribution is by flash power, flash distance, and aperture & ISO, whereas the latter two also affect the ambient light's contribution.
