The factory wires are really cheap and poor quality. I replaced mine after 10,000 miles to prevent any issues.
I just did these Livewires, Screamin Demon Coil, and new Plugs. I am now getting about 10-20 more miles per tank. I can't say I felt any power gain but I will say it just feels smoother all together. Considering their coil costs exactly what a new one costs from autozone I didn't feel that bad about the purchase and now I have an extra coil lying around (Factory One) should this one ever go bad.
You MAY get slightly better fuel economy, like mentionedabove, 10-20 miles per tank or so. The hotter spark will give more complete combustion, but any increases in power on such a small, low power engine will go unnoticed since it'd be so small, if any.

If you are doing it for a performance gain I would not. They are around $190 and you will not notice any difference. On the other hand, if your coil went bad or you need new wires then why not. There is nothing wrong with dressing up your motor with matching color wires.

I guess it's possible but I doubt it. I put 37's on my Jeep when it had about 12,000 miles on it and it has almost 50,000 now and I have always got around the same amount of miles per tanks. The only time I have seen a difference was when I did headers (a little extra) and now when I did the ignition. The biggest benefit is I don't have to worry about burning the factory junk up with aftermarket headers, these can take a lot higher temps than the factory wires.
