Looking at learning C++, anyone got any useful tips, best practices & trusted sources?

Assuming that you have some coding experience i'd give Accelerated C++ a go. Its slightly dates but is one of the few resources available that doesn't spend three chapters walking through loop constructs.
After you've gotten comfortable take a look at Scott Meyer's series on C++.

Stephan Lavavej did some awesome tutorials on the core language and the STL, which he is a maintainer of. A bit dated (2010) but is a good intro to c++11.

Also, if you're using Linux, perf is amazing for performance profiling.
