The LDK is pretty much identical to the UDK so the best place to start would likely be YouTube. Once you have the basics down and are ready to get into specifics there's usually a decent amount of people hanging out in the ROTT chat room so don't hesitate to ask for help there.

cool been watching a few vids found one on interceptors youtube it was a live stream about the level editor and makeing a map from the original ROTT that kinda showed me how to make enermys spawn and useing the lifts etc just gota work out how to exit levels and a few other bits that will help me finish my SP level soon any ways thanks for the help :)

hey i dont supose you know why my maps making a low level constant noise as all i did was copy a trap from one place in my map to the other and its now making a long sine wave kind of sound when i test my map and the exsample maps what can i do??

remove the sound actors and try again, if problem is gone there was something with that sound actor, if not, maybe a wrong audio device setting in windows (try stereo).
