Brian, nutrition is the easiest part of training, IMO. Sure, we all have little questions about certain things here and there, but don't overthink it too much.
Eat good quality food and you will be fine. If you need more carbs, eat more sweet potatoes and fruits, be easy on the dried fruit and fruit juices though.
I eat a bowl of oats with protein, peanut butter and cinammon on rest days at times because I want to, but usually I am no grains (unless a crave strikes then all bets are off).
