One thing you might think of packing in your light kit are neutral density filters. I have a stack of 1/2 stop filters in my lighting kits. You can control ratios with them if you need to dim the lights and the power if your strobe head is turned all the way down. I use clothes pins to hold them in place. These filters work for me because I do tabletop work and the lights are fairly close to my subject. I remember my first light kit, I was obsessed with light and the language of light. My favorite source of inspiration was Dutch masters and Impressionist paintings. Great old BW movies are a good source of ideas too.
