Second Joshi guide but yout you can do better than that.
We have a list for all level, some of them are free to download (just like Joshi), others are books and websites that for beginner level
As for websites and blogs, there are only a handful of them out there (this is a niche field after all).
Every site has a different flavor and attracts a fairly different audience. You have to sample them all, see the kind of questions asked there, the kind of members and how they answer.
WARNING: some sites are not very newbies friendly as they carter to the working professionals. As I said, it will take time to learn the in and out of each site.
I like this site http://quant.ly/
