I don't install windows, just paint them 
If you stain the windows you don't want to use any caulking on the wood that gets stained. Even when painting, the window itself doesn't usually get caulked but the trim does. Use a siliconized acrylic latex caulk after the primer has dried and been sanded but prior to the finish paint.

Replacement windows fit into the existing frames, so they get caulked to the outside stop, to block air and water. The air space between the old frame and new, should get sealed with a non expanding foam. I like DAP Foam, because it will not overexpand and push out the window frame. As Mark said, don't caulk any interior trim until stained and finished. You might then use a clear caulk or one the same color as the stain. At any rate, use a latex or paintable caulk.

I usually run a bead of caulking on the stop and install the window,screw the window in make adjustments and then run another bead of caulking on the outside to seal the window against the stop.

so we caulk on the INSIDE ; along the side stops and upper stop? then along the outside, sides and upper?
when painting or caulking,use a paintable'stainable caulk AFTER we have painted or stained?

There is no such thing as a stainable caulk! There are caulks that can take an exterior stain butnone of them will allow the stain to penetrate the wood like it needs to on the interior side.
It is best to prime and sand wood before applying the caulking. This keeps the wood from drying out the caulk [which might make it fail] and of course caulking doesn't sand well.
Generally there is no need to caulk stained/poly trim but if you have to, use a clear acrylic siliconized latex caulk after the stain and 1-2 coats of poly are applied. Clear latex caulk comes out of the tube milky. You need to let it cure [clear] before applying poly/varnish over it.
