I meant to point out that in a 2400-lb coupe, you may not have a lot of room for weight reduction without digging into the comfort of the car. You can shop for lighter seats but those are usually race-oriented, and look kind of cheesy, especially in a daily driven commuter. Weight reduction helps a lot, but only if you're in a lot of stop and go driving. If you're on the highway most of the time, there isn't a lot of advantage to be had from it.

+1 on the lighter wheels. If you can find Insight wheels (especially if you can get the Insight with them!), you can shed some pounds at each corner and they should bolt right up. Less unsprung weight also means a nicer ride, which is important in areas with rough roads.

Check tire pressure. That's another no-cost item. I run about 42 lbs in each tire and it's worth about 2-3mpg on my car. It's well above the door placard recommendation but below the sidewall limit spec.

Taking off the PS belt means, if you like the steering without, you can remove the PS pump entirely. There's a bit of weight reduction right there. It also frees up a tiny bit of space under the hood for wrenching. Save the pump, of course - when you sell the car on, the absence of power steering will probably put every potential buyer off your car.
