I found http://japaneseclass.jp really helpful. It has many lessons in both Kanji characters and their meanings, as well as vocabulary. It also keeps track of what words/kanji you need more practice with and will bring them up more frequently in quizzes. Hope this helps~ :)

Kanagrams will help you learn kana to a very high level! 

If you are looking to speak Japanese, there are many videos on youtube that have helped me. I've learned a lot of grammar and other important aspects of Japanese on youtube as well (and my textbook of course).
