No, he doesn't need a later bedtime. My 5 children ages 1yo-9yo all go to bed at 8pm and wake up around 7:30am. I'm wondering how much your son naps during the day. Too little sleep during the day can result in poor sleep at night and cause them to wake early. On the other hand, too much napping during the day can also result in early waking because they have had enough sleep. The goal is to gradually move all sleep to the night time, so naps very gradually become shorter until they're gone. At 1 to 1 1/2 years old, my kids are always taking a 2 hour nap in the morning (10-noon) and a 2 hour nap in the afternoon (2-4). Right around 18mo the morning nap goes away, and they switch to taking a 3 hour nap after lunch. This afternoon nap gradually gets shorter (just because they start waking a little earlier) until finally it goes away close to 4yo. This amount of daily napping and about 11 hours of sleep at night is really what children need to be healthy and well rested so they're not fussy.
If your schedule already reflects a healthy amount of sleep, I would consider blackout curtains in his/your room to keep the sun from waking him. I would also cut out giving juice to drink and avoid all extra sugar during the day...too much sugar during the day can really affect night time sleep.
Also, at almost 1yo he really should be sleeping through the night. Because he's still waking 1-2 times, I question how well he's really sleeping. The only time I hear anything from my kids at night is when they have to pee...unless they're sick or something.
