1) Determine what your competition goal is. Fun is obviously why we're all playing this game. But fun means different things to different people. This is a sport after all. You need to decided if you're playing just for the sake of playing or if you want to win. The answer to that will go a very long way in determining how much $$$ you should spend on equipment.
2) Once you've answered #1, don't spend a single penny on equipment until you go to as many matches as possible and try as many different configurations as possible.
3) If you absolutely HAVE to start shooting right now you can go ahead and buy the most inexpensive equipment you can find. But that approach tends to cost more in the long run. "Pay one, cry once" is an old cliché that has its merits.
