Your first two points are good for GMOs, but the other two are the result of breeding efforts rather than lab work. There are no GMO cows and chickens in high commercial production, and FWIW no GMO tomatoes either.
Then again, GMOs and conventional breeding taken to a commercial extreme get tangled so often it's hard to separate them in these sorts of arguments.
The first GM crop to be licensed for human consumption in the US was the Flavr Savr tomato, which contained a trait that improved their shelf life and appearance. It was a commercial flop and taken off the shelves after a few years on the market.
