Ohhhhhhh you have so much to learn my dear ........... :-D NEVER try to change his "bad" habits. They're only bad in your opinion -- he likes them just fine or he wouldn't have them at all. Instead, just embrace your Chosen One in all of his original, stock-from-the-factory glory with all the good and bad and in between that makes him him. If you don't try to change him or mold him into your idea of the "perfect husband," then he probably won't try to change you either. Along the same lines, accepting his habits without reproach also means he can't give you a bad time about your "bad" habits either.
All in all, you'll enjoy more peace in your life, better (and more productive) communication, and much less drama and uproar ... and get to sick back and laugh out loud at him when he's a dumb ***. :-D
