I wouldn't worry about the uneven terrain for flats. If you get a flat because of the uneven terrain, then you must have tubed tires and are not inflating them enough to keep the rim from pinching the tube between it and the tire.
It's normal for the thin butyl tubes to leak down in just a few days. So check your tire pressure often till you know what rate yours leak down at. Latex tubes are even faster. Both for rolling resistance (good) and for losing air (bad).
