Yes, a shift kit with low gear ratios will definitely help in headwinds and steep hills. Keep in mind that human power doesn't help much, when the engine is driving the same chain.
You could also buy a generic windshield from a Chinese scooter on ebay. They are relatively cheap and easy to install.
