If you're just starting Japanese.. well I would suggest going to this website: http://forum.koohii.com/ You'll find posts with -tons- of resources there. I personally would recommend you get ANKI, download a PDF of Remembering the Kanji somewhere and get a good anki RTK deck and go through the book. I studied Japanese for about 6 months and then found out about RTK and stopped studying Japanese to do that and learn about a lot of kanji. For me it was one of the few good things I am really glad I did. The other two were taking a class at the local community college (we were lucky to have a teacher who thoroughly taught the grammar) and the other was taking online Japanese lessons with real Japanese tutors. I didn't use iTalki but I imagine it would be about the same. I did small group sessions and it helped with some grammar but more than anything it made me conversational.
