Try out different things. Your light kit is limited so you may need to rely heavily on available light, like Kar Wai. Experiment with your gels on your shop lights like there's no tomorrow. Get to the sets ahead of time and do various lighting arrangements, checking out ideas you've considered in advance, e.g. storyboard your lights. You will need a video monitor on site to see the impact of your setups. Have an assistant who knows how to move hot lights, so that you can give directions, based on what you see in the monitor, to your assistant on how to adjust the lights. Your wattage should not cause a problem, but you will want to survey the wall socket situation to avoid blowing a fuse. In a high wattage on location situation, lighting assistants run around testing sockets in order to spread the watts over more than one fuse.
If your bar set has neon lights, you may need to adjust cam shutter speed to prevent distracting fluttering of this type lighting.
A high percentage of short independent films have compromised sound. The public notices and complains more about gritty quality sound than they get torked about the quality of lighting (unless the shadow lighting is really nasty with obvious video noise). Be as fussy with your audio as you are about your lighting if not more so.
