I did not sand it smooth. I thought about it, but decided against it in the event that either I did a poor job or if the color didn't come out right I could go back and it would look stock. I also didn't know exactly where to tape it off so I left myself an out. If I end up having to do it again, I'd sand it smooth, use a real paint gun, and probably have a shop mix up a better paint match. I just used the rattle cans from paintscratch which ended up turning out better than I anticipated.
