Your requirement are quite easy and common.
1. Either you install a photocell or a timer. The advantage of photocell over the timer is that if there is power failure, the timer's setting could be out. However there are timers with built-in batteries but will cost more. Photocells can be purchase from the electrical supply shops for around RM30 each. Get the better quality ones.
2. This basically the emergency lights. It comes with its own built-in batteries. Can get them from the light shops or the electrical shops.
