To add another site like the ones Olofantur linked, there's also http://ffxivcrafting.com/equipment for crafting needs.
Generally speaking though, if you're getting dungeon loot at-level, you'll probably be fine. Unlike FFXI, there are no skills tied to equipment and until endgame content, pretty much anything at-level or a higher item level (if it's green, blue, purple gear) will be better than anything before it.
The game does a decent job of feeding players decently good gear towards the end of 2.0 content leading into 2.1+, from what I've heard. (Adjusted quest rewards).
