You have gotten some great advice so far. However, I have a few things to add.
If you're serious about wanting to get into breeding, I would first look into what morphs you like, reguardless of what it is made of. You may like Pinstripes, Albinos, and Lessers as stand alone morphs, but you may find yourself not liking some of their combos as much as others. So I would first look into your favorite designer morphs, and trying to build up to produce them. Nothing like creating your own favorite 2 or 3 gene morph yourself!
If you want to start with hatchlings, start with females. They take longer to grow and give you more time to focus on what male to buy. And in the meantime, the prices will have lowered and your optiones widened.
Also, I would highly recommend investing in a rack system or two while building your collection. You may not need it right away, but it's definitely good to have. I'd rather have empty unused slots then not enough. Especially when the time comes for breeding, you won't have to worry about buying everything at once.. It's already there.
Take it slow, find out what you personally want to accomplish and you will be fine. Good luck!
