I think #1 is a great idea. You will make your house more your own, you will feel a lot better about yourself for doing it, and your W will surely notice the changes.
#2 and #3 both seem forced. You are trying to create these fake scenarios just so your W will notice changes in you. What you need to do is make the changes for real w/ yourself, so that you don't have to create these things, they will just happen anyway. I know you are looking at ways of meeting new people and making new friends, which is great. Keep up w/ that and some time when your W is dropping/picking up D, someone WILL actually happen to call when she is there. You won't have to fake it or force it that way, it will just happen on its own. Don't discount the fact that she might be able to see right through things that you are faking for her benefit.
With all that said, the thought of you putting lipstick on so you can create some cigarette butts for your sidewalk is pretty hilarious.
