Good tips!
-Never heard of side gapping. I'll look into this.
-I doubt it's as simple as a hotter or colder plug in a very highly tuned engine, but my knowledge is very limited on this!
-Low octane fuel contains on average (marginally) more BTUs per volume. It's not much, but to my knowledge is is a real effect.
-Low oil makes a ton of sense to me. Faster heatup, less friction. I too run thin oil. I've read studies on it, and engines which switch to a thinner oil actually run cooler; the difference in internal friction is enough to make a measurable difference in operating temperature, but also slows down warmup time.
