Are you using the HF or VX transmission? if I remember right the HF tranny will give you slightly better gearing in 5th gear and altho that will not help with the A/C using more gas, it will help the rest of the year.
I would say that if the A/C is running as much as it is, make sure that it is in perfect working order, that the belt is not to tight, that it is cooling properly, that the coils are clean and that the fan under the hood is working so that it is not running more then it needs to run, if you can, it might be worth figuring out how to reduce the cabin area by putting a clear partition behind the drivers seat so you are not cooling the huge greenhouse-like back portion of the car, that would allow you to reduce the load on the A/C and thus improve your mileage without reducing comfort.

How is the rest of the car? do you have light weight HF wheels and properly inflated tires? is the alinement right? stock CRX HF exhaust?
