How to learn to play a bass for dummies?

-So I want to learn how to play a bass. I love the sound it portrays. It just gives me a ***** every time. It's something I've been wanting to do for a while now. I think I'd be good at it. I have long fingers, too. So maybe that helps. I need to want to learn how to read the tabs and stuff. All the numbers and stuff don't make sense. I want to change that before I buy one. Yes, I know I sound like I'm just wasting my time and money, but I honestly will put forth the effort. Any websites I can go to?
