How much faster would I be with better wheels & tires?

My road bike is a Trek Domane AL3. A lower end, aluminum-framed road bike.
Wheels are: Bontrager Paradigm, Paradigm SL or Affinity Disc,
Tires are: Bontrager R1 Hard-Case Lite, wire bead, 60 tpi, 700x32mm

I was poking around researching tire pressure, and this simple calculator says:

More important than tire pressure is choosing supple tires that offer both more speed and more comfort than stiff tires.
Here are my questions:
  1. I'm guessing that those Hard-Case Lite tires are not considered supple, but I sure like the fact that I've had zero flats in over 2,000 miles of riding it. How many more flats am I going to get (all else being equal) if I get "supple, high-performance tires"?
  2. How much faster will I be? I typically ride 15-17 mph, where 15 is comfortable at around a 150 heart rate and 17 is maximum effort at 175 heart rate.)
  3. Someone once told me: "Get rid of those stock wheels and get something decent and it'll make a big difference in your speed." How much, do you think?
Thanks!
