Priund--herbalism/alchemy-easy, fast,having health, mana, and intellect potions available is helpful. The downside is there isn't much money in it, so she auctions the linen she takes off humanoids as a money maker.
Wartar--mining, blacksmithing-time consuming but fun. And I can twink new guildmate warriors' armor and weapons for all classes. The ore mined is used for smithing. Other materials such as leather from skinning are sometimes needed, but Wartar gets it free since he keeps friends supplied with armor.
With other toons I have done mining/skinning-the most money.
Enchanting-didn't like it-takes too long to level up. I haven't tried it with tailoring though which I hear is a good way to green items to disenchant.
With the gathering professions you get the ability to find the ore or herbs but only one finding ability can be used at a time.
Professions are often geared to the specific needs of your toon. So smithing would be useless, for example, to a priest.
