Look for: CppCon, Meeting C++, Microsoft's "Going native"
I can personally recommend any talk by: Bjarne Stroustrup, Scott Meyers, Stephan Lavavej, Sean Parent, Andrei Alexandrescu
Of course, there are many more gems (e.g. Chandler Carruth's talks are great if you are interested in a compiler author's perspective).
As far as reading materials go, I know of two books that seem to cater to your background:
Stroustrup: A tour to C++ (http://www.stroustrup.com/Tour.html) Meyers: Effective modern C++ (http://shop.oreilly.com/product/mobile/0636920033707.do)
I personally only own the second one, but have already heard good things about the first one as well.
The C++ core guidelines (work in progress on http://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines) should certainly also be worth a read.
Of course, for actual practice, reading/contributing to open source code seems like a good start. Maybe have a look at this list: https://github.com/fffaraz/awesome-cpp/blob/master/README.md
Edit: The "Awesome C++" list also has a "Resources" section that links to even more material...
