Not necessarily thoroughly. However, I would suggest looking in a couple of 
sections: Program Space Strings, and Integer Types. You don't have to write 
your own stdtypes.h. Just #include <inttypes.h>.

Also take a look at some of the UART source code that can be found in various 
User Projects in the AVR Freaks website, Academy tab (up top).

No. Setting, clearing and toggling bits in a register (or any variable for that 
matter) is done through C's bitwise operators. I suggest looking in a good C 
reference for that. Alternatively, you can look at:

Have a look at this tutorial by Colin O'Flynn:
