what lvl should i start worrying about better equipment and how to get them? do i hunt specific monster for them or craft or just buy at npc?
Short answer: it depends on your build. I’m a quite new player too, but with my current wizard/elementalist, I simply used all stuff I got from the quest rewards. Ponctually (basically when your level reaches a new tier), I check the market place for better stuff – there often are a few better items at a very low price.
