As suggested, keep up with your main quest line and class/job quests. These quests will gear you up to at least level 20-30 gear. I only recently went to the market boards to purchase my first hq level 42 gear. Biggest mistake I have made was not keeping up with my main quest line, now I am like 35 levels behind in my main quests cause I did too many side quests and farmed early level dungeons for gear too much. Main thing is to have FUN and try not to get too frustrated with the maps.
