Hi Jenny,
Kua numbers are not related to the positive/negative aspects of the flaying stars. If you are Kua no 3 it has nothing to do with conflict. Kua numbers are related to your heavenly luck (date of birth) and show in which way you connect with the Universe (via your auspicious personal directions).
It would be good to place all the cures/activations related to the 20 year feng shui. When you do it, take into account the annual feng shui. For instance in the NE you would place a fountain according to 20 year, but in 2014 you have a violence star in the NE. In this case I would place still water only, a fountain would stimulate the violence star. I believe that you power star would be in the NE of your house.
You can find information about the power star in level 3 (page 17) and in level 4.
Have a double happy feng shui manifestation.
