Genki Japanese and Japanese the Manga Way have high approval rates.
Put all all your new words into an Anki deck, short sentences on the front, pronunciation and English translation on the back.
Whenever you don't feel like studying, dig out your old Anime or other Japanese media and watch them again, this time with the subtitles -off-. (Or buy new ones.)
Start buying whatever Japanese media interests you (manga, anime, video games, movies, biographies of the AKB47 members) and try to understand them. When you are going through real native material it is probably futile to add -every- word you come across to Anki.
Whenever you don't know what else to do, come to this site and randomly poke around the 'Learn' menu and see if you don't find something interesting.
Once you can understand a short simple article in Japanese, check out lang-8 and start posting there.
