You should check out guidetojapanese.org. It has a very nice grammar guide that you should read through because it explains things nicely and orderly.

The genki books are good ,there is a good website called japaneseclass.jp where you can learn japanese for free,as for kanji,I reccomend using some of the courses on memrise ,they are pretty good ,I have'nt tried it yet but I heard anki is good also for vocabulry,for listening ,what i do is i go onto tunein radio and listen to japanese radio stations
