I strongly recommend Fowler's Modern English Usage. It is directed towards native speakers but would clearly be accessible to you, and is exactly the sort of book you seem to need.(I'm a native English speaker and I find it enormously helpful).
There is a fourth edition of Fowler's now available under the slightly changed title Fowler's Dictionary of Modern English Usage (ISBN 9780199661350), but I am not familiar with it. The copy I have is the third edition (ISBN 0198602634) edited by Burchfield. A great many "purists" don't like the Burchfield edition because he is less prescriptive, and more accepting of language-change, than was H.W. Fowler, the editor of the first edition but that is also one of the things I particularly like about it. It is pretty clear when he deviates from the original Fowler prescriptions because he uses phrases such as "the esteemed first editor of this book was of the view that ..."
In addition to addressing the use and meaning of particular words (for example, there are entries for "every", "everybody", "everyone" that consider issues like plurality or singularity), there are also extensive entries on grammatical issues like split-infinitives, gerunds and prepositions. Even if it turned out that it was not exactly the book you needed, I have absolutely no doubt that it would enhance your command of English and your confidence in your ability.
Just in case there is any question about Burchfield having been competent to produce the third edition, it's worth noting that he was, for thirty years, the editor of the Oxford English Dictionary!
