Dan - call you utility and ask them if they will give you a free energy audit - those are common in Oregon.

you do want low-e glass.

you may want to increase ventilation in the attic - best if you can shut that down for winter

do you have vents in the "ceilings" of the roof that runs all the way around the house outside the walls?

also state if you know many of the terms for house construction...
