Stephen,
Well before any other gas-mileage consideration, you must fix the DI. "3 cylinder running" means 25% of your fuel is going out the tailpipe without providing power to the car, which is going to have a severe impact on fuel economy.
Personally, I'd recommend the new DI cassette - the "blue" ones that have recently become available seem to be the cheapest. It seems that DI cassettes are essentially a "wear item", and this is not the kind of thing you want to buy used. A used one could "expire" in a month and your money would be wasted.
Otherwise, here are a few general tips to improve gas mileage. Tip #1 is accelerate as gently as possible and short-shift like crazy. Basically, never give the turbo a chance to do its thing - on flat terrain, upshift at 2000 RPM or so, or at very least obey the upshift light.
Tip #2 is anticipate slowdowns and lift the throttle or shift into netutral and coast. If you're always either accelerating or braking, you might make a good race car driver but will get crummy gas mileage.
And last, minimize use of air conditioning. I've read in a number of places that on the highway, using the A/C instead of rolling down windows can improve economy. In my experience with 2 9000's and a 9-5, this is not the case.
With my Aero, commuting 20 miles each way, about 75% highway on flat terrain (Florida, USA), the above 3 tips can make the difference between averaging 23 MPG and averaging 30+!
