Normally the WN would be "cannon", but since quite a few things changed between LN and WN, and a lot of major plot-points have been more-or-less the same since the LN, my vote is that the LN is now the intended cannon (moreso, since it's basically a rewrite, and just about everyone  who has ever had to rewrite something would gladly prefer the newer one being the official version).

Also, I'd love to help edit (especially with formatting and grammar-related issues). As far as content goes, though, I'm a LOT more familiar with the manga and anime, so I'm not sure how much that would help.
