To answer the second part of your question, he doesn't sound like he has changed anything in regards to getting up and going to bed. But we turned the clocks back almost two weeks ago and sometimes it takes them time to adjust. Heck, it takes me time to adjust! I am still waking up an hour early.
As for not sleeping on the bed, I would suggest crating him at night if he won't stay off the bed. You can work on the "off" command and every time he gets up, you tell him "off". You may have to assist him off the bed the first few times, but I am sure he will learn what that words means pretty quickly. I don't mind my dogs sleeping in bed with me, but my husband doesn't like it. So they go to bed with me and then get down when he comes to bed. And he wonders why they love me more! LOL
