This thread pretty much goes through all the motions you're planning; give it a good read: Arduino nano schematic
This would probably also read provided you use a ceramic resonator for the 16MHz clock source; if you use a crystal add 2x22pF as shown in millions of MCU schematics.
Or alternatively, how about you show some schematics you have found but that you have trouble interpreting, and you ask your questions so we can clarify?
