Doh! Thanks!nk @Ronglos was answering your question on the torque setting for the lug nuts - 100 ft. lbs.
I don't see the value of a jack stand in changing a flat tire. After jacking the wheel up; place the spare under that corner if you want extra safety. After pulling the bad wheel off; now put that underneath before taking the spare out.
So 100 ft/lbs?
