2005 Kawasaki Ninja Ex250?

I've had this bike for about a week, I'm just starting off, so I have a couple of questions. I've seen a few times people talking about crosswind on the thruway, I would only have like a two mile ride on the thruway to work, should I be nervous with this little bike? I'm also wanting to change the color of the two stripes on the side, they are orange, and in my opinion it doesn't go good with dark blue, but I noticed they are just decals, does anyone know where I could find the proper style decals in a different color? Any pointers would be greatly appreciated thanks!
