When is everyone putting your baby down for bedtime?

My baby is 10 weeks and we have been doing our last feed around 10/10:30. That puts us right at 7-8 feeds a day since he is starting to sleep 6-7 hours. We put him down for a nap around 8:30 ish and then will wake him for one more feed around 10:30 and then let him feed on demand through the night. When should we start having an earlier bedtime? And as far as feedings go do we still need to aim for 8 feedings? He eats about every 2.5 - 3 hours a day.
