Prior to take off, look sideways out of the windows. That is where you need to be on landing! (Probably the best landing at night tip I have ever had.)
Also, use the descent angle lights (if available) such as PAPI (Precision Approach Path Indicators) or VASIs (Visual Approach Slope Indicators) which will allow you to get your final approach under control from the top of your final turn. Like all things related to flying, if you start early and get ahead of the aeroplane, things generally work out better!
Use the taxi or landing lights! That's what they are there for.
I'm sure that with a couple of solid circuits under your belt, the whole 'division of attention' thing will improve measurably.
Relax, get the aeroplane under control at the top of your final turn, divide your attention between inside and outside all the way down and enjoy it.
