I have a vast collection of needles, straights, long and short, circulars and all the various connector sizes there, then the DPNs, short and long... bamboo, nickle, aluminum... There is simply so much out there that you can quickly feel overwhelmed.
I would look at knitting supply sites, and look at the different options they offer, see what is in which kit, the prices, etc. Then come back here and do a quick search for the brand you've chosen, and then make your decision.
I would say that if you are a beginner, that you may want to try out the different types of needles, buying a cheap pair to see what you prefer. Some folks prefer nickle, others will not touch anything but bamboo, others love plastic or acrylic better than their own dogs. It's really up to you and what you prefer.
Be sure to let us know what you chose and what you're knitting with them.
