I would also suggest Tailor and Jeweler. You can fill 11 of your 13-14 equipment slots (6 pieces of armor, 5 pieces of jewelry, 1-2 main weapon(s), and 1 underwater weapon) by taking those 2 professions, and Jeweler is almost 100% gatherable from nodes around the world. Tailor Materials are mostly from monster drops. So the 2 crafts don’t overlap with what materials they need.
That way you can craft the vast majority of what you need, and you only need to buy a few weapons for your character throughout the game. Note: It is very hard to keep 2 crafts up to your current level though. You will need to buy materials for tailor along the way, thats for sure. I did these 2 crafts myself, and with the TP under construction back then, I had to give up on tailoring until it was fixed.
