I do think they probably would have still put you on Red at your current weight. If you need to drop down later to keep losing, you'd go to Blue, which is the same exchanges with a smaller protein portions. (basically wherever you got 8 oz you'd get 6 and where you'd get 6 you drop to 4 oz). Both of those plans are typically used for those who exercise a fair amount or have an active job.
It is quite likely at the 182 there were close to moving you to Blue, although they usually keep you at the current plan until you stall out on losing for awhile.
I've bought Luna bars on amazon for a reasonable price. I've often used zone bars too. I've tried a variety of bars, and haven't found a huge difference as long as they contained a goodly amount of protein. I think it is the protein that keeps you from getting hungry for awhile.
If you wish to do less than 5-6 hours of working out, you could try purple. Which is about the same as Red with one less starch and half a protein (I think that is what it is anyway). Perhaps if you start out kind of slow at the gym, you could do purple for a short time and then ramp up to Red once your workouts get up to a level that you are feeling the need for more calories.
