Wiring Check: Prizm + Tri-Rebel R/G/B

[Wintermute]

Hello all! Yet another babe in the woods looking for a little wiring wisdom...

I've read the manual cover to cover, and crawled the forums for a couple days now to make sure I'm not asking any very common questions yet again (though I'm sure I still will), now I'm just looking for a pro's double-check of the wiring on my Prizm + Tri-Rebel R/G/B build so I don't torch a $115 sound card doing something stupid.

The biggest question I have is: The manual for the Prizm clearly shows a diagram wherein the resistor is inline between the negative pads of the LED dies and the board, rather than to the positive pads (first image) I'm confused... I always assumed that resistors went along the positive connections so as to reduce the current BEFORE it gets to a component. Am I missing something here?

Any other glaring issues with my planned wiring?

Thanks in advance for any insight!
