The biggest piece of advice I can give from my recent / current rise through newbie gear - is to just keep leveling. Don't get too focused on getting one great piece of gear at a low level. You level so quickly on SoD, and the amount of plat you earn ramps up so quickly, that it's almost pointless to try to "equip" even every 10 levels (until 50+ really). Most classes can subsist (at least in a group) in cloth/leather + newbie gear.
There are a couple of items I would HIGHLY suggest putting the effort into working on, as they will stay with you a long time if not forever.
Start working on your Newport Ring quests (check the wiki). First stage can be done solo (by most classes) by 25 or 26, and step 2 by 28-30. This is a very nice ring for the level, and once upgraded to the fifth version is fantastic.
Also, if you have the patience, do the bandit head turn ins for newport tokens to turn in for Newport Faction. Get to Ally with newport and get a GREAT neck piece for a low level that also has newport gate! Which, even once the stats are useless will continue to be useful forever.
