Dew questions

Hi all. I'm trying to figure out the best application of the (passive) dewshield on my CST with these cold nights.

Should the padded bit go over the tube?
Should the shield hang out as much as possible?
When leaving the scope out for a couple of hours before using it (with the cover on) is there any point applying the dew shield at that time?
Is there any point wrapping the OTA proximal to the dewshield with something insulating, like a kitchen towel?

Also when bringing the scope in at the end of a night's viewing, should I leave the cover off for any dew to evaporate?
Are the little heated strips worth using, if power isn't a problem?
Any other hints?
