The other guys answered your questions pretty well, but I want to interject my $0.02 about #6. There should always be a spark when hooking up the your last connection because the caps are always discharged when you remove the battery.
Depending on which ESC you got: a "true" V3 with wires directly soldered to the PCB, or an V2 upgraded to V3 with connectors on the PCB instead.
What might be happening is that the first couple/few times you plugged the packs in, you ablated the heatsink on the MMM. The heatsink is VERY close to the power plugs, sometimes even touching. When you plug the batteries in, the heatsink shorts out the pack for an instant and basically vaporizes the itty bitty contact area between the heatsink and connectors. After a while, all the aluminum is ablated away and you no longer see a large spark.
Or, your battery connectors could have gotten pitted from the sparking during the first few connections.
Or, you just got better at smoothly hooking up your battery connections, which helps reduce the spark.
