You already have enough, but will need lights real soon.
I see people riding to work with Jeans, flannel shirts, sandles and they all make it in.
If your butt gets sore over the 14 miles you might want to pick up a cheap pair of bicycle short liners. I bought a cheap pair when I first started and it helped alot.
Your route should be your biggest concern right now, the rest will take care of itself over time.
