Le Chuck you are my new best friend! Good job on knowing just the 6 infinity gems haha. So the resistors are essentially the contact points? Ill probably use colored lights, and clear gems, that might be the easiest. I appreciate it!

If that's the case you'll need different resistors and it'll be easiest in parallel because some colors need different resistors than others. The resistor goes on the negative leg of the diode. Easiest to pick out your LEDs then figure out what resistor each will need. If you can find colored gems you'll save yourself wiring headache but if you can't it's not that bad. Also, if you want to power off a single 9V you can do an array like this:
+----|>|----|>|---/\/\/----+ R = 150 ohms
+----|>|----|>|---/\/\/----+ R = 150 ohms
+----|>|----|>|---/\/\/----+ R = 150 ohms
which is three parallel lines of two LEDs each, so you could have all, four, or just two lit at once.
