Well, theres always the crafted set:

You'll need a goodly number of levels first.
Otherwise, farming bone chips, HQ animal hides and deathfist belts will be one of your main staples for plat.
If you're cool with buying from someone in EC (rather than obtaining the drops directly), once you get a magic weapon and up to lvl 10ish you can also start killing Wisps for lightstones. Lightstones are decent XP if you turn them in in SRO to the merchant camp there. Greater lightstones are good XP & money (you get a tomb that you can NPC for 9p i think). Gather up a bunch of those & run over to the camp (you could sell them too if you need).
I searched the wiki but couldn't find any quests that are specific to dark elves with rewards that a warrior could use.
