Performing an upgrade on US.

[arusiasotto]

Howdy, in need of some advice here.

So for V-day, m'lady got me a US Phantom Initiate V2 double saber. But she somehow messed up the color on one blade. US customer service being what it is, we are SOL. Which is why after my first saber from them, I said never again. However, Princess didn't know. So since I have to replace an LED anyway, I decided to add sound to them. US Obsidian is way too pricey! Like sweet Jesus. So now I am looking at a Nano Biscotte. Mind you, this is two sabers that connect together, but I figure as a double blade it only needs one sound card, I can add the second later.
Parts list:

NB V3
NB V3 MWS Header/Wiring Harness
12mm AV Mom Red Ring Switch
65 ohm/0.026W resistor for AV switch
Li-Ion 18500 3.7v 1400mAh Battery modue with PCB
2w 20mm Speaker
??? Led resistor

Not sure what resistance is required for the orange led they use.
Also not sure i calculated the AV resistor right?
Am I planning the parts right for such an endeavor?
