It really depends on what you are trying to show and what angle you are using, especially since you are using zooms.
Since you are working with zooms, I'd suggest limiting yourself to certain angle stops rather than the whole range. Something like 18mm, 35mm, 55mm, 85mm, 135mm, and 200mm. Or whatever stops are marked on the lens. You don't say if you are using film or digital. If it's film, the 18-55 is a wide angle and the 55-200 is a telephoto. Wide will put more into the image than the eye normally sees. A telephoto puts less in. Wide will exagerate distance between objects (front to back, not side to side). Avoid wide when getting close to people. It will exagerate sizes of facial features. Nose will be large and ears will be small because the nose is closer to the lens. Telephoto will compress distance. At 55mm, the lens will see things about the same way as the eye does. It's "normal". Try to make you focal length choices (mm) based on this. If you are using digital, 35mm would be considered "normal".
Since you are shooting at night, you'll probably have to use flash. I personally hate on-camera flash, as it's one of the main things that says "snapshot" to me, but everyone has to make do with the situation in front of them. Depending on your camera, you may be able to adjust your flash output. You could try upping the ISO and using a wide aperture (low f number) so that you can dial back on the flash, making it not as harsh. You'd need a bit of light where you are shooting for that to work well though.
If you have a separate flash, get a cord for it so you can hold the camera in one hand and the flash in another, high and off to the side.
Hope it all goes well, and good luck.
