Ceramic Coating should make a noticeable difference in temp, I've been told by a guy that did it on his Eclipse.
I don't see how wrapping could hurt.
Another issue with wrapping headers is they contract and relax and this has caused some headers to crack, but on the stock cast iron manifold I don't think it will be a problem. As to rusting. The thing is cast iron, I think a little rust will not hurt a thing and that's if it isn't already rusted from the factory.
