Gamefly is not on the official list of retailers either but they offer pre-purchases as well. Anet has said before that that list was still being updated so it's not finalized (the list itself used to be in wiki form[guildwars2.com]).
And yes, all Pre-Purchases (whether digital or physical) come with all the bonuses. Just don't confuse it with "Pre-Orders", it's not the same thing.
