Seriously, there's sometimes no right or wrong filmstock, just think about what you would need in terms of daylight/tungsten, grain/no grain, all of that. The best thing to do is to do a lot, and I mean a lot, of tests and copy down all of what you do, the lens, focus, f-stop, filmstock etc. so you can redo the results if needed. Get a good light meter too. Also, focus with a telephoto lens is usually a shallower depth of field, that is harder to keep in focus/less is in focus at once, whereas a wide angle has a greater depth of field. Your f-stop also has an effect on your depth of field.
