Fun! I was the same way!
I bought myself a Fender Squire. Great, inexpensive bass.
Perfect for starting out.
I would recommend lessons if you have the money for them.
That, or get tabs for songs you like that aren't crazy difficult. Then play along!
The trick is to keep playing. The more you play (I.E. Practice), the better you get. I know that sounds pretty obvious, but you wouldn't realize how many people get a guitar, play for a week or two, and then complain that they aren't very good when they donly play it for a few minutes every few days. That's ridiculous. If you actually want to get good, set aside an hour (Or two) a day to just playing it. Picking around, working on chord/note progression, taking lessons, playing along to songs with tabs, or practicing tabs.
It takes work, but having the skill to play an instrument, and play it well, is freaking awesome.
Have fun!
