Suggestions to light up a rectangular-shaped Chinatown store

Hi I would appreciate some suggestions how to set up lighting in a Chinatown-based appliance and electrical supply store that will be the set of an episode of "consumer-sense" infomercials. The location is mainly lit with fluorescent lights with tracked lights on the sides to add "neatness" to the products. The store itself is narrow(about 12 feet wide), but its depth is quite deep (maybe 25 feet deep or so). This is typical of many Chinatown stores in Vancouver. As with many Chinatown stores here in Vancouver, the store is cramped full of products and little room to put up even a stand for the camera. This production is none-to-low budget for equipment (all the cheap lighting equipment is owned by the cameraman, I'm just the lighting coordinator). We will feature a host and the products that are environmentally-friendly in the store. What are some options to light up the scene without getting harsh on the shadows? Or is lighting needed at all?

Thanks
