puglist/rogue/ninja jobs to help gear in present and future?

[Niwashi]

If you level carpenter, armorer, leatherworker, goldsmith, and miner, you should cover most of your bases. Again, level 15 in the other classes is just to improve the quality of your gear (if you care about that)

But then those crafting/gathering classes will need their own gear as well. That comes mainly from Weaver for clothes and Blacksmith for tools.

EDIT:
If the list is getting too long, you could probably leave out armorer. Since the only class you're looking at that would need it is Lancer, and you'd only need to level that far enough for its cross-class skills, there are few if any ARM items you'd need. If you only level lancer to 22 you wouldn't need any armorer items, since LNC uses the same gear as the other DoW classes for the early levels, not splitting out to its own gear until level 23. If you level LNC the rest of the way to 34 for the Blood for Blood skill, then there's armorer-made gear you may want at levels 23, 28, and 32 (if you don't have equivalents or better from dungeon drops). That's few enough you can just buy them.
