I don't remember too much from my three years of PA32 ownership except this one: when you lower flaps, the nose will come up. If you do an approach to a short runway with flaps, the runway will be under the nose and will be invisible. You will be looking through the side window to do the landing.
Also, don't forget to properly close the nose baggage door, if you don't, it will open right during the landing flare and sit on the windshield. After the PA32, which was a nice load hauler, I moved to the BE36 which is a real pilots aircraft, much faster but with less useful load.
