Two things I would like to mention. First, it's never a good idea to take important photographs with a new and unfamilar camera. You really need to take a few rolls of non-critical photos to get the feel of it. Second, even with a fast film exposures are going to be long. This rules out using the camera as a handheld. It also requires you to either use a tripod or to locate appropriate places where it can be placed to make it steady.
