It's pretty easy V, just take the list you posted earlier to V-LEDs website, then shop by part #. The website automatically sorts the bulbs by price high-to-low, and there are 1-5 brightness ratings beside each one. I would say you want to be careful about getting the brightest each time - for example, you may or may not want the horn light to be as bright or brighter than the corner markers, since you can actually see them while driving.

+1 on the V-LED spider brake lights, I have those too and they are awesome.
