Regarding the sound, do you know where you will be shooting your movie? Will it be in the one location or will you be moving from one place to another? Have you done a recce of the location(s) and listened to the sounds to see if they are low or will they dominate the sound track when you come to shoot. Is there anything you can do to lessen the background noise? Like move people to another room or switch machinery off for the duration of your shoot. If you are outside, noises from wind, traffic, planes flying overhead, ambulance/police sirens can ruin the soundtrack so go for a directional mic with a wind sock or 'muffler'.
