Autolite 3924 + TW heads = couple questions

Hi all, sorry for the newbie questions, but I couldn't find the answers on Trick Flow's site.

1. What should I gap these plugs to? I'm using a stock ignition.
2. There's a steel ring that comes with the plugs. Is that to be used with TW heads? If so, does the flat side face the head, or does the lipped side face the head?
3. I see all over Trick Flow's site NOT to use anti-seize for header bolts and intake bolts. What are you guys using? And do I use anti-seize for the plugs, or just motor oil like everything else says to use?

Thanks in advance,
