So, first things first, WHERE you remove weight from is as, if not more, important than how much you remove. Rotating mass is better to remove than fixed mass, unsprung weight is better to remove than sprung (i.e. supported by the suspension) weight, weight up high is better to remove than weight down low, and weight at the ends is better to remove than weight in the middle. You also need to take the car's weight balance into consideration: a Mustang is a front heavy car, so you're better off taking weight off the nose than off the tail.
So, that being said..
The dog bone is there for harmonics reasons only. Scrap it.
A/C is about 35 lbs.
Rear seats really aren't that heavy, they're relatively low and in the middle of the car. Not a huge advantage to scrap 'em.
Front seats on the other hand *are* fairly heavy. You can save 30-40 lbs replacing them with lightweight racing seats.
Tubular suspension bits save weight. Going to a tubular K-member/A-arm/Coil-over setup can be worth 80 lbs off the front end. Tubular control arms out back will let you scrap the quad shocks.
Hood is already fiberglass, so not much weight to loose there unless you scrap the insulation.
Lightweight wheels are HUGE. Wheels are both rotating AND unsprung, making them some of the worst weight on the car. Saving 20 lbs off the wheels is probably worth pulling 100 lbs out of the pasenger compartment.
