I agree about keeping that expensive sleeping bag away from the fire and resulting sparks! Depending on a fire for warmth may not a great idea, anyway, if you've read Jack London....

Condensation is often a function of insufficient ventilation, so don't make that tarp shelter too tight. Remember that your body puts out a lot of moisture at night.
