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.

I did some scheme in my Programming Languages class and enjoyed it a lot.
Though I'm not sure what it can teach me about game dev.

In my compiler construction class (toy lang to MIPs assembly via C++, Flex and Bison) my professor told us we should read the entire C++ standard.
I'm a little iffy on doing it...
I'd like to become a C++ expert, but all that study takes a lot of time; I'm running low on time now that I'm out of college.

Do you actually find time to study that extensively with a 9-5 job?
(Thanks for the other links. I'm checking out the Smalltalk and AR kit)
