I guess landings really depend on the jet you are flying. Some airframes just sit in the runway without needing to much input, just throttle managment. Some others require a lot of pilot input just until they touch ground. I guess if you tell us what jet you ar looking for we can help a bit more.
For me in general, one of the most important things is speed and thrust. If you get this you will do good most of the times. I guess the idea is to gain or loose altitude by throttle management... Also coming in with power is much better than gliding in, in the event you need to go around.
Also getting to know your model and all the good and bad habits it has, will help you out a lot.
