What Wolfey says, and:
Assuming we’re talking about ascended:
If you already have an ascended medium armor set, you can always decide to swap stats from your former set, into zealot’s. Which is much cheaper then acquiring a full new armor set. On how to do so, check: http://wiki.guildwars2.com/wiki/Ascended_armor, scroll down and check Attribute Change.
Same goes for Weapons: http://wiki.guildwars2.com/wiki/Ascended_weapon
Trinkets, you’ll have to have a bunch of Magnetite Shards, which you’ll get from completing Raids. Also don’t forget to unlock the mastery: leyline forsaken thicket, rift traveler to get to the merchant which sells you the zealot trinkets for magnetite shards.
If you happen to have very much magnetite shards, and some gold, you could also buy zealot armor and weapons from that same merchant.
