I'd suggest you go to 1,600 first. That way you should feel fairly comfortable as far as your hunger level is concerned...rather than take the chance of not being satisfied and going over.
If you look in the Healthy Eating Guide included in the Starter Kit there are some Sample Menus for the 1,600 calorie level for you to get an idea of how to distribute your calories throughout the day -- whether you make your own menus or follow the Samples.
You might also take a look at the chart of Exchanges on p. 20 of the same booklet. It lists the amount of servings, from each food group, at each calorie level. Some people (especially if they were on the old WW plan) find counting exchanges easier. There is a listing of the Exchange groups in section 5 of the booklet too.
Please let me know if you need anything else.
