I usually aimed for 4-5 points at meal time and then the remainder for snacks (I only had 21 points). It will vary depending on your points and any considerations like I have like hypoglycemia.
I highly recommend subscriptions to Weight Watchers and Cooking Light magazines. They are super for meal ideas and the meals are always excellent. Have yet to have a dud recipe from either magazine.
One of my biggest lessons was to add salads, fruits and veggies to meals whenever possible. They're extremely low in points (and I believe will have zero points under the plan coming out soon) and will help fill you up. Also, be sure you're choosing foods high in protein so you stay full longer.
Most of all, don't forget your splurge items. Have small amounts of your craving item when you have extra points. You'll stay on track much better if you do that than if you treat this like a diet.
Good luck! I lost 18 lbs. on WW and reached my goal weight just a couple months ago. It's a great program and I follow the principles now to maintain my weight.
