Just to add to the posts above, a good method to learn kanjis and words is "reading", not only this but, if possible, rewrite the whole text copying every kanji and try not to translate it to your mother language, make sure you can comprehend every sentence in japanese and read every kanji present in the article.
After some time you will start to recognize patterns in the readings, and develop self confidence to read things by yourself, this exercise is really good because it puts your vocabulary, kanji knowledge and grammar, to test.
