Well, for starters, 5'5" and 156 pounds is pretty good. As the expression goes, "if I wanted a woman with the shape of a 10-year-old boy, I'd just date a 10-year-old boy."
Now, to answer your question:
To permanently lose weight, you must drop 3600 calories from your diet for each pound. To lose 2 pounds, you'd have to eat 7200 fewer calories per week. While 100 calories a day seems like a small amount (one less donut / coffee every day) it's harder than it looks.
If you do that, you're going to put your body into "starvation mode". You'll lose muscle, not fat, and you're almost guaranteed to binge and get into a guilt mode. Ease into it and exercise more. Bike to work, jump rope, and do push-ups / sit-ups before bed.
Don't skip breakfast.
This depends on your height and exercise routine, but you should probably have around 1800 calories to maintain your weight or 1500 to begin losing weight.
1500
Eat 10 calories per each pound you want to weigh. Therefore 10 calories x 130 lbs = 1300 calorie intake per day.
A woman that weighs 138 pounds could burn anywhere from 50 to 100 calories while walking for 20 minutes. It really depends on how fast the woman was walking.
A sedentary women needs about 1,600 calories.

125 or less 110-195 pounds. 200 or more is overweight! You should probably try to lose a few pounds if you are 195. It depends on the woman though. My mom weighed 105 pounds at 33, and she is almost 40 now and weighs 120.
It depends on how much she weighs, how old she is, and her activity level. But on average about 1,800-2,000 to maintain.
