L.M.
Hi. My son is 3 yrs., 5 mos. old. He wakes up generally about 8:30, takes a nap at about 12:30 until 3 or 3:30. I let him have lots of physical activity between 3:30 and 6 (which is dinner time). Wind down time until about 8:00, then bath and bedtime is 9:00 when his sisters go to sleep. This routine has worked his entire "toddler-hood" so far. The physical activity is key if you want him to go to sleep earlier. Too much sleep or sleeping later into the day gives toddlers too much energy and not enough time to dispense of it. :)
Best of luck.
