I think learning the readings is a waste of time because there are so many on and kun readings for the same kanji and you wont be able to tell when to use them, just learn vocabulary instead, and yes reanding vns with text hooker and a parser will help you a lot, grammar and vocabulary all together, the bad thing of this is that sometimes it's not really fun to read the novel because you are studying and not just reading but it's better than just to study from a book or plain text

use anki or memrise for the vocab, start from n5 and so on.
btw dont read something just because it is easy! read something that you like even if it is not the easiest thing out there, reading something easy but boring will be a chore and you wont learn anything, trust me on this, pick something harder you will struggle a bit more but you will end up learning.
