Reddit mentions of Strategies for Reading Japanese: A Rational Approach to the Japanese Sentence

It can be slow going, especially starting out, but once you get the basics down there's no harm in just diving right in to something you want to play and just doing some serious dictionary diving/googling to work through it, and honestly you can learn a lot from bashing your head against something like that. So don't feel like you have to spend years studying before you can get anything out of it -- that can be a motivation killer.

One book and one article I really like. Both are pretty linguistics-y so your mileage may vary:

Also:

http://maggiesensei.com/ can.. get a smidgen weird for various reasons but it goes pretty in depth

Iiiii will say that I didn't find the A Dictionary of Basic/Intermediate/Advance Grammar terribly useful. A lot of the information in them you can find elsewhere. I thiiink japanesetest4you.com covers a lot of the same stuff, but is searchable (although I think some of their example sentences come from the Tanaka Corpus which has a reputation for Having Weird Translations).

Japanese: A Comprehensive Grammar, 2nd Edition DOES seem to cover a number of grammar points I haven't seen explained elsewhere but it's expensive so yeah.

(Also I have a personal tool that lets you look up words by: A) Listing out the components/radicals in the word as a while so you don't have to find the entire kanji if you don't know what it is and B) Pulling up components/radicals by configurable keywords so you don't have to like hunt through a grid: https://github.com/amccour/RadKey-4.0/releases The documentation's lacking but I could try to give a walkthrough if it sounds useful to anyone :S)
