The only time I turn off IS on my lenses is when I have the camera mounted on a tripod taking longer exposures. Otherwise I just leave it on, even when I've got a shutter speed of something like 1/1250 when it shouldn't be needed. I guess a lot will depend on the implementation of IS on a camera by camera/lens by lens basis...
At higher shutter speeds and action shooting I'd turn IS/VR off because there is an additional shutter delay whilst the IS system stabilises. I remember reading that the average delay went up about 100ms depending on the camera/lens combo. But, that was a Nikon setup, so cannot comment on Sony or Canon.

As I've noted before on this forum, the real issue on whether or not to use image stabilisation is how strong and steady your arms are.

I leave it on (if I'm using it) - since my IS is in-lens, the image I see through the 'finder is stabilised with a 1/2 press of the shutter release, so no lag is added. Withy in-body IS, I might be tempted to turn it off if it was unlikely to be of use but only if it drained batteries faster.

For Canon lens this was the case in early ones but now it not matter apart from saving battery

no one answer will be different for different lens and one person to the next.
The reciprocal of the focal lenght
A good guide is to always use a speed over the length of your lens so if you were at 200mm then you would want over 1/200 sec. If you have a crop sensor camera as I understand yours is this will increase again so would be 200x1.5= 300. So you would want a shutter speed above 1/300.
This is just a guide and as highlighted above can vary depending on the photographer and equipment.

You should turn IS off when using a tripod, as generally if your using a tripod your shooting at low shutter speeds but the camera is still, the IS can attempt to stabalise momvement when none is there and intorduce camera shake.
There isnt any issue when using high shutter speeds. Just remember to turn it off when using a tripod.
