There are a lot of skills and spells you can train as you progress, each of which costs money. When you can afford to, you should train all the abilities that your class trainer offers. If you're completely broke, it's fine to put off upgrading abilities you rarely use for a level or two so that you can upgrade your most-used abilities. If this happens, you should ask yourself whether you are spending too much money on buying unnecessary equipment upgrades or leveling production trade skills. Be sure to save enough for class abilities and riding training before spending money on other things. This assumes you're earning money at a rate where buying skills makes a difference at all. If you have a hundred gold from two gathering professions by level 20, those skill ranks costing a fraction of a gold won't make any difference to your purse.
Although the Battle Pet Trainer will only offer to teach you your race-specific companion, it is possible to add all of these pets to your collection. You can either find them in your faction’s auction house or you can create a character of the race whose pet you would like to learn. Using your new character, you can seek out any battle pet trainer in major cities. After you learn the pet, you can delete the character; the pet you learned will not be removed from your collection.
