I personally like the look of 18" wheels on an accord. Go for a 18x7.5" wheel with 225/40/18" tires.

If you're on a budget, you could lower your car using Tein Lowering springs or a set of H&R's. Mate those with a set of Koni of KYB shocks and you're good to go. This setup should lower your car about 2" while still maintaining good ride characteristics. If you could spend a little more, I'd opt for a set of coilovers.
