Stop the night time pullups, and when he poops in his underwear, have him throw them away. He'll hate seeing his undies go. Of course, when he's not looking (taking a nap or something) take them out and put them in the washer. Afterall, underwear is expensive! That's what we did. When he goes poop in his underwear, flush it and make a big deal of saying "bye poop!". Once he does go poop in the potty, make a huge deal of it, "Oh, we're so proud, you're such a big boy....". Is he excited about starting school? We told Kiwi that she had to be pooping and peeing in the potty before she could go to school, that she wasn't allowed to go in her undies if she was there. All she wanted was to go to school, so that was the big reward, the main motivation for her going in the potty. She didn't poop in the potty for about two weeks after starting to pee in it. The pullups just confuse him, he knows its okay to go them, so get rid of them.
