Yes, it will try to load the player.pl from the zone folder and if not there, it will load it from templates if one exists there. It would be nice if both could load and run simultaneously so you could have global stuff for player.pl as well as zone specific stuff.

I believe that for any scripts located in the templates folder, the server has to be restarted for them to take effect. Not 100% sure on that, but I think that was the conclusion I came to last time I tried playing around with it.

Also, some notes on your compilation of quest wiki pages:

EVENT_ENTER and EVENT_EXIT are both related to proximities, so they don't work from the player.pl. They are triggered when the client enters or exists a proximity around an NPC.

EVENT_SCALE_CALC is for item quest files, specifically for items with something set in the charmfile field. This event is for setting how much you want an item's stats to scale based on a percentage. Here is an example of a custom quest I made for a custom charm I have on my server:

/quests/items/CHRMTitanium.pl

sub EVENT_SCALE_CALC 
{
	if (defined($qglobals{titanium_relic})) {
		$questitem->SetScale($qglobals{titanium_relic}/10);
	}
	else {
		$questitem->SetScale(0);
	}
}

Note that the quest is stored in a folder name "items" instead of a zone name. Also, note that CHRMTitanium from the file name is what needs to be placed in the charmfile field for the item.
