Thom,
I have nothing to add to your original question but I do have some input on the roof vents your contractors suggested - do it!!! I installed an attic fan several years back as these are supposed to help with the cooling bills. Our attic fan ran almost continuously from mid-morming to late evening in the summer. We had our roof replaced and had the roofers install the roof vents... the fan has not run in the last two years. We noticed that our house also remained cooler in the summer.
