1. what tools/supplies are need to do a proper and strong vulcanized patch repair?

The cold vulcanizing solution is the best you can do for "strong vulcanized patch repair". There's really no such thing as a hot vulcanizing repair (and "cold vulcanizing" isn't really vulcanizing at all). The trick of flaming the patches is just a way to remove the solvent quickly instead of waiting for it to evaporate. A proper "cold vulcanizing" should create new chemical bonds between the rubber of the patch and the rubber of the innertube, so it's not easy to remove. You would have to use a chemical reductant that would break down the structure of all of the rubber in the area. That said, a poorly applied patch can sometimes be peeled off because the vulcanizing isn't done well.
If you have the misfortune to get a puncture through a previous patch (which seems really unlikely, but I guess could happen), that's probably a time to throw out the inner tube.
