Since you're still in the process, this seems like a good opportunity to write a tutorial and worklog. :o)

Here are a few calculators. Just input the source voltage, forward voltage, and forward current.

LED Calculator, Array Calculator (http://led.linear1.org/led.wiz), and Color Coder (http://www.dannyg.com/examples/res2/resistor.htm).
