My ds is 8.5 months old, and his bedtime is around 7:15 or 7:30. It used to be 8 pm around 6 months old, but we moved it earlier, as he would be cranky & tired earlier. He has pretty consistently been waking up around 7 am. He occasionally wakes up earlier, but is usually a 7 am riser.
Also, go with the flow on the naps. Sometimes my ds still needs a late afternoon catnap to get him through to bedtime. Sometimes he doesn't. It depends on the day, and how long his naps were that day.
And yes, I actually found him to sleep better when I put him to bed earlier - even half an hour!
Good luck!
