Depending on your front sway bar so heavily isn't a good idea either. Sway bars increase lateral load transfer. If you have a large sway bar in the front, you're transferring more load to the outside front tire. This is taking grip away from your inside front, and since its a fwd, its making you slower. The sway bars should be used to fine tune things, but not as a main dependent.
Also, just because civic guys use a certain combination of spring rates doesn't mean it will work for the accord. The motion ratios, sprung and unsprung masses, chassis, suspension geometry, etc are all different. The only way to really know is to measure. What you're after is a rear ride frequency slightly higher than then front. However, since fwd's are nose heavy, this is going to result in your spring rate still being higher in the front. People that run a higher rate in the rear are fooled into thinking the car handles better because of how the rear end rotates...but its really just hurting overall grip.
You want a soft front bar and stiff rear bar so that you have as equal as possible of loading on both drive wheels, and the stiff rear bar will help put load on the front inner tire because of diagonal weight transfer.
You really need to measure the car to know for sure what spring rates are good, and until then all you can do is guess. Being a fwd, you want as much forward weight distribution as possible within your class too. That will change up your spring rates as well. Remember, your rear will be proportionally stiffer than the front in terms of ride frequency, but as far as actual spring rate goes, the fronts will still be stiffer. Assuming your CB7 is fairly stock as far as weight placement goes, I would try something around 600lbs front, 400-450 rear...but again, you really need to measure the car to know for sure.
