Can I remove the strainer so that I can feed a tube down through the wye to pump out the water in the pipe below for a camp winterization application?

Yes you should be able to do that.

What is the temperature range/rating is this strainer assembly rated for?

I drain and remove my assembly when temperatures are expected to be below freezing. It lengthens the life of the unit.

Does this come with rubber washers (like in a hose connection)? I see it is IPS not NPT so i assume it is meant to seal against a washer.

No rubber washers were included. You will need to wrap the connecting pipes/PVC with plumbers tape or some other sealer. On my 2nd year with this backflow and seems to be holding us just fine.
