alyssa-well, i think if your ds seems happy and generallly well rested, then he is getting enough sleep. the routine you posted actually looked really good to me. he's getting about 13 hours sleep total,right? that is exactly what my dd gets. she gets 11-12 overnight, and then depending on her night sleep she will take a 1-2 hours nap. yes, he will have a rough patch of several weeks while making the switch while his body sorts it out. if you think he can handle it, you can try pushing everything later. but if he is exhausted by naptime, maybe wait a few weeks til he is better adjusted, then try pushing it a bit later. when we first started the switch, gianna was still waking up in the morning at her usual time of 6 am, which made it hard to keep her up til 12. but then one day she just started sleeping in. now i sometimes have to wake her up at 8! it's awesome! so maybe your lo will start sleeping in on his own. but if he seems well rested that is the most important.
