Are there resources on the web on how to prune a douglas fir tree (about
70
feet tall) to prevent wind damage?

Unless you are trained for this type of tree work with all the necessary
equipment, the only resource you need is the phone number of a certified
arborist. One does NOT prune or window a 70' Doug fir without having a great
deal of tree pruning experience under one's belt - translate: do this for a
living. To even consider doing this on your own is foolhardy in the extreme.
BTW, a certified arborist can give you a hazard assessment first - this will
determine whether or not your tree even needs thinning or windowing to
reduce wind damage.
