how much air should I put in my tires

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

FWIW, it's what my wife and I use now, and since changing over to it a few years ago I've had zero pinch flats. I'm 175# and my wife is 100#.
Wow, my bike + rider weight is about 155lbs (135 + 20) and it recommends 70/87 psi (f/r) for my 700x23c tires (maxxis detonators). I'm currently riding with 90/100, a bit harsh at times on some bad roads. Will give a lower presure a try.

Don't forget clothes shoes, water, etc can add ~10#. But yes, you'll notice a big improvement. My wife is ~110, and she uses 60/75 with 23s. For me, I actually had to add a few pounds to the rear to 115 and lower the fromt to ~95 and it made a difference in feel from 110/110.

Fill them to the max so they're harder. Use helium instead of air, because it's lighter.
