Well, that's pretty much all you can do on this site, other than Readings. If you're looking for grammar, I recommend Tae Kim's Guide to Japanese.
I used Memrise for a while to learn Hiragana and Katakana, as well as some sentences.
I also found a blog a while back for motivating stuff, it's alljapaneseallthetime.com.
