Pet Training is not a big deal mate. You'll just need Bite or claw ranks from other pets around and armor upgrades from pet trainer. Boar and serpent are good chooices because you can feed them with free mage bread. I know cats/raptors are cool but you'll need fishing or meat to keep them. Food is expensive at vendors when you've nothing.
For hunter training, don't touch anything if you won't need it seriously like distracting shot. You'll need gold for mount. This should be the first goal.
I always go for mining/skinning or herbalism/skinning at levelling my first char. Crafting professions make things harder at levelling. Herbs are very cheap at first areas but they get expensive when you reach end 30's lvls at auction. Ores are always great. I never make bars. Skinning idoesn't bring great income at first levels but if you find a leatherworker, (your mats and with a small tip) you can have very cheap items and your arrow/gun pouches.
