Congrats on your new Spirit. Seems we are almost neighbors - I'm next door to Sherman.I bought a 2009 Spirit in August. When the weather got cold I added a Memphis Shade windshield with quick release. I remove it when I clean my bike, and my bike stays spotless. The windshield is a blessing in cold weather.
I won't change my stock Honda seat, it's comfortable for me, and I like the look of the sloped over, clean bare look.
