ummm.... I think you should go hang out at your local scuba shop for a while. It's free to hang out. Just introduce yourself, say that you want to eventually take a class but first are interested in learning more about it. Divers love to talk about diving, dive equipment, dive experiences, dive theory... really we just like to talk about anything to do with diving. There is just too much for you to learn it all from a forum, and you may be getting some lingo that you are unfamiliar with here. Also, you probably don't want to buy equipment before you even learn what kind of equipment you will like.
Welcome to scuba and happy diving!
ps - I am so jealous, I would love to have learned how to dive while living in Hawaii!
