Where should I start Game Dev now?

So, I have CS degree, MMO dev experience in a native language (think WoW and its scripting language (LUA?), except standalone,) and a lot of 2D games developed in C# XNA.

I want to move to C++ but I'm not sure where to start. At the moment I'm looking at GameDev.net.

If your job is to be a C++ programmer then unless you're irresponsible or incompetent you should have the standard memorized front to back, and be able to cite it like the bible.

If you are not able to do this, please use the standard as reference till you can, and yes read it every night.
