First, NEVER get LEDs from radioshaft.
They suck.  You might as well  close your eyes and imagine it lighting up.

Second, never connect LEDs directly to a power soure. Always use a resistor. (unless it specifically says not to.

Third, go with power suply hookup over USB.  It's too easy to fry USB, and it drains current from anything else on the bus.
