I have had good luck with the Thermotec insulation. I have it on my firewall and around the brake lines. You can also get it for all lines and headers. I have no heat at all in my foot box and yes it can also be used under the carpet and will cut down noise but there is cheaper insulation for that which works as well. As for wrapping the headers they make that also and it will keep the under hood temperature down quite a bit and you may even pick up three or four horsepower.
