Never heard of that app. I  personally use Anki decks for practicing kanji and weblio/jisho as dictionaries.

Though, I wouldn't recommend memorising readings by themselves, as it's just unnecessary confusion. You won't always know when to use a specific reading aside from guessing when to use kun or on readings, especially if the kanji has a lot of readings. The 日 in 日本 is a perfect example, since 日 is read as "ni" practically in only that one word and its derivatives. And readings that end in things like ち or つ have a tendency of becomming っ in compound words. So instead, it's much better to learn a word that uses a specific reading. Two birds with one stone. And it's easier to remember then, especially as you learn more words that use the same reading.

And yes, there are stroke order rules. That's why I recommend learning a variety of kanji just to feel how they work. Then you can pretty much guess how to draw a kanji just by looking at it.

You don't really need to know much vocabulary to learn grammar. Actually, I recommend learning grammar early, since knowing how the words in a sentence are related is more important than knowing every single word in the sentence. And if you want to read novels, you're definitely going to encounter quite a bit of grammar. Occasionally, even some advanced-level grammar. I'm not sure how good the grammar lessons in your app are, but I personally used Tae Kim's guide to Japanese grammar. It's sufficient for learning basic and intermediate grammar. You might not understand the grammar perfectly on your first read (especially the all the conjugations), but if you keep returning to the lessons, you will get a hang of it over a few times. As they say, repetitio est mater studiorum.

As for notebooks, I'd say that it's better to have an electronic one for looking up kanji. Easier to find stuff when you have tons of kanji. Again, I recommend learning the kanji as parts of words. I.e. look through all the meanings of course, but also note down some of the words that it's used in (unless the kanji itself is used as a word on its own). A written notebook is mostly useful for practice, not actual lookup.
