In all cases , if you want to go sure, you have to put a resistor in each led group (a led group is formed by 1 or several serial wired leds ). Because your leds don't have exactly the same characteristics, you can't just put 1 resistor in front of a parallel grouping, as showed on this web site. It may work, you may also have problems (1 led shining much brighter than others, or 1 led being destroyed because this led got most of the current of the group). If you know enough about electronics, then you don't need those wizards. If you don't know enough, you should always use a wizard which provides you drawings and values you can trust. About FAQ and troubleshooting database : we're thinking about it. Stay tuned Cya
