1500 calories feels low given your activity goals. See how you feel - if you are finding that you start having cravings or are sluggish during your workouts, you may need to adjust upwards.
Otherwise, I think it looks good. I especially love that you will get your kids involved in your activity. Good for mommy AND for them! I need to do a better job at this. I tend to squirrel away & take it as "me time". A nice break for me, but I want them to learn from exposure the importance of formal exercise as well as just living an active lifestyle.
If you aren't already, may I suggest taking a multivitamin & calcium? I think both are important when we are restricting calories - especially if exercise is to be a significant factor in your weight loss.
Keep us posted on how it is going! You sound like you are in a great place emotionally & ready to go, go, go!!
