I guess you have most bases covered. I would add, make sure the Intake is a Cold Air Intake and every now and then give the engine some really hard driving to avoid any carbon build up ( a few hard acceletaions should do the trick, and if you see dark exhaust fumes when you do it, it means you did it right, now if it continues with the smoke, then something is not right )

Good luck.

Other than making sure your tires are properly inflated and the AC is off, the best fuel economy mod is the driver. Drive slower, accelerate slower, maintain momentum. I get 30-31mpg in mostly city driving short trips with the AC on. I could easily drop that to 27 or so if I drove more aggressively. Likewise, I could probably up it to 33-34 if I relaxed a bit.
