Here is a list of the crafting gear that you should look at getting as you level up. There are obviously many more options but these are the most important ones. I am not including the GC gear since I don't know which company you belong to…

Also, I am not including gear that is specific to some classes with the exception of the new hats. Mostly these are not a major improvement anyway and take up inventory space if you level several crafting classes.

As you can see, you should look at changing gear at about L17, 28, 38, 48.
