I think Tom Venutos e-book: Burn the Fat, Feed the muschle, is worth every penny!
I just started his program about 6 or so weeks ago and I am already leaner than I have ever gotten trying to do my own thing.
A couple of things that might be really helpful to you in that book are the guidelines to what foods to eat for maximum results, how to figure out your calorie needs and the whole concept of zig zagging.
I'm about as tall as you and am on a 1500 cal diet split into 5 meals a day equally, then eating 2000 cals worth of food every fourth day. Before, I used to hover around 1200 cals a day and not zig zag and nothing much ever seemed to change. But now I see changes.
If you can afford it, I highly recommend you get it, it makes for a fascinating and motivating read!
Good luck!
