As far as I can discern, definitive rules of grammar (including spelling and punctuation) in Russian are regulated by the Government via the Institute of Russian Language, attached to the Russian Academy of Sciences.

In this regard, D. E'. Rozental et. al. have produced the following, evidently, Government backed text that both lays out the rules and, to some extent, explains the logic behind them.

It seems that "Rozental" is *the* authoritative reference source for matters pertaining to Russian orthography. To my knowledge, there's also a schoolbook "Rozental" that is pretty much standard issue.
Concerning phonetics, syntax, morphology, etc. the Institute of Russian Language refers to this site:
