As far as sound goes if you have a small crew and your budget allots for it, a Sound Devices 7-series recorder is compact, light, and manageable by one person (I'm perfectly capable of mixing and booming simultaneously if I have one of these) and they have things that may save you due to lack of people (an adjustable pre-roll record time, nice file naming capabilities, etc). If the budget doesn't allow for one of these, a Marantz compact flash recorder with large cards will do the trick.
