Right view and right thought are part of Prajna which means wisdom. Right action, right livelihood and right speech are part of Shila which means morality. Right effort, right mindfulness and right concentration are part of Samadhi which is concentration. The right view involves understanding the Four Noble Truths. If you read any of the books available by the Dalai Lama or any of the other teachers of Buddhism they make quite a point of telling you that Buddhism isn't a matter of faith but of understanding.
Right thought is thought that is free of lust, anger, cruelty and lying.
Needless to say it is almost impossible to have your thoughts free of many of the negative emotions but by practicing Buddhism you learn to recognize those sort of thoughts as they appear and you can send them away. I'm speaking of the ability to meditate which teaches you to empty your mind. When you practice the tenets of Buddhism you are able to recognize the thoughts of lust, anger, cruelty and such which might come up and you can deal with them. Yes, right speech means no lying, no gossip, no cursing, no vain or harsh talk. It's another aspect of teaching yourself how to be a better person.
