It never hurts to move away from white bread, white rice, white pasta for anyone.
I eat wholemeal, or seeded bread.
Brown rice, wholewheat pasta.
Chocolate is very occasional now.
I don't count carbs at all, and am active, so can't really cut them out, as I manage a lifestyle that involves eating out, and grabbing food on the go.
I found just balancing the calories and achieving a stable weight on a normal healthy diet worked out best for me for that.
You need to test, it's the only way to find out what suits you, and what effect food has on you.
But you results are certainly going the right way!
