Hello there imtheonlysane1here! ^^

About learning Japanese, um, well everybody has their own way of learning and certain methods may be preferred by some while others dislike it. Anyhow, I will tell you what I know based on my knowledge.

The idea of focusing your priorities on the grammar is very good, because you cant speak the language with empty words without knowing how to use them, right? However, based on my experience, if you give all your focus on one specific thing you will most likely end up trying to memorize too many words at once, which will result in forgetting most of them, if not all.

So my suggestion is basically:
Prioritize your grammar studies.
While your studying grammar, try to learn the words you come across at the same time as well as their kanji, that will give you a bit of a variety on the things you learn, which results in a better memory.
When you?re done with your studies, move over to kanji studies and increase the vocabulary you have left to learn.

Some good resources I?ve come across:
Tae Kims grammar guide: Free grammar guide online as close to a book as you can come, detailed information starting from Beginner Lessons to Advanced Topics. Very good site check it out ^^
Basic Kanji Book 1 & 2: Teaches you the first 1000 kanjis with their origins, stroke order, on-kun readings, as well as example words that they occur in. Very nice book for learning kanji.
Kanji odyssey cd: Has the first 2000 basic kanjis on a cd with their stroke order, example words, example sentences, and pronunciation. Although this one doesn?t teach the kanji origins.

There you go, I hope that helped and good luck with your Japanese studies! (^^)/
