Here's what I intend to do:

- study Japanese the Manga Way
- study Tae Kim
- study JLPT 1-5 grammar points from http://japanesetest4you.com/

Is that good? Can I omit the Tae Kim part or will I still learn new things in it after JTMW? What could I change/add to my plan? I start with JTMW instead of Tae Kim because it seems funnier and it teaches a lot of spoken Japanese expressions.

Don't worry for the vocabulary part, I just finished RTK and I'm working on it. I just want to reach a good reading proficiency (manga, light novels and video games).

Thank you!

You need to have a way better understanding of the JLPT grammar points than that website seems to offer. A lot of people like the Shin-Kanzen Master books, and I agree. You don't really need to study N5 or N4 grammar though--that will all be covered by Japanese the Manga Way.

But it doesn't matter; you're thinking too far ahead anyway. Just do Japanese the Manga Way and then reassess the situation.

If you are not studying for JLPT (self studying for, I don't know, consuming Japanese media?), then this would suffice, provided you have *everything* covered in Tae Kim on your tips. Rest of the grammar you can look out as you encounter them.

Thank you!

I'm not interested in taking JLPT at all, I just thought studying those points would help me to learn more grammar in a systematic way.

When you say "this would suffice", do you take the JLPT part into account or just JTMW/Tae Kim?

Studying only Tae Kim would have been ideal (I hate multiplying sources) but I'm under the impression that it won't teach me as much slang and particles as JTMW.

What I want is to be able to parse sentences and search grammar on my own. I noticed that grammar is often only vocabulary by the way.

I study Japanese to understand video games. Maybe I'll buy some manga and light novels but video games are my top priority and I essentially learn vocabulary from that world.

I study grammar from here sometimes http://www.tanos.co.uk/jlpt/jlpt2/grammar/usage/
I focus on the sentence examples, I'm not one for technical rules. And this site has lots of sentence examples too http://www.jgram.org/pages/viewList.php?lv=3
I've added some grammar sentence decks to Anki recently. I feel like I hardly need it; when I read/watch things, I don't feel like I'm missing out on stuff grammatically. But as I want to get more advanced, I feel I should get the more advanced grammar points down too. So if you feel that way too, you might like these sources down the line.

I'm of the same mind as yukamina. I feel that the best time to study grammar is once you have seen the constructions a few times and can get a gist for the sentence. Once you can stumble through some actual japanese, you can take some time to go through the grammar points to get a more sophisticated understanding.

I haven't read JTMW, but I've heard very good things and it seems to align well with your goals. If I were you, I would just study that book and only add additional material if yo feel a great need.

I can't recommend the Dictionary of Japanese Grammar series enough. Just the first book is enough to get you through your first 2-3 years with the language (it's that comprehensive, and the intermediate and advanced levels are just as great (even though the grammar you'll find is a bit more rare with the latter).
