This link provides a lot of useful information. As for the use of anti-seize, the shop manual makes no reference to using any. Also, I have read that if it is used, it must be a nickel based anti-seize, and not the more common copper based one. The Beru web site has additional information in regards to fitting their plugs which can help you decide the best course of action to take.
