I was taught that the key things for flying at night were
1) after take off, basically fly on instruments for the first 3-400 feet to avoid illusions. (I can't remember what it is called - help please ) , but just once I forgot and did get very confused for a couple of seconds).
2) On landing, basically the same as a day landing except keep a bit of power on to make the let down more smoothly (1000rpm on a PA28) and look down the runway to judge the flare - but - be aware of the runway lights in peripheral vision. When you get the sensation of them being around shoulder high, flare gently until you get the sensation of them coming up to your ears. As a general rule that should equal success.
Of course, these are my experiences and really you should discuss them with your instructor before trying them out.
Flying at night can be so wonderful that a slightly teary landing has occasionally happened to me.
