The first couple of books are canon (and reasonably good too)... Then they changed author and they become terribad. Reasonably sure that they (the later ones) got officially un-canonised once it was realized how blatantly wrong they were...

Of course, the lore around Batarian women that does exist is simply there to justify Bioware taking shortcuts in species design by only making males for most of the species...

As far as I know, anything by Drew Karpyshan (I think that's what his name is) is canon because he was the lead writer for the video games. The one I think you need to avoid is the one by William Dietz, who also wrote the awful Halo: The Flood adaptation.

The comic books are all solid. I highly recommend them, especially if you like fleshing out the stories and motivations of a number of characters.
