Basic wiring as you described it should work just fine.
However, I gotta ask, how many LEDs and Resisters did you get for your $29.00?
One can acquire 2mm Tower LEDs from LighthouseLEDs.com for $0.21 each, unless you want to buy in quantity, then you can get them for as low as $0.13 each. The 2mm Tower fits perfectly into the light socket on the blue box GP/SD 7 thru 45 if not more. They also have resisters starting at $0.10 each.
