Welcome to EM! I am interested in your lowering + taller tires. My paranoia is that my "one size up from stock" tires would rub on the inside of my wheel well. When you got your HHR, did you have the impression that the wheel well had plenty of "room to lower", or ?!?!?!?!?
As already said, items 3 and 4 are debatable for FE. Another alternative to the Trifecta tune is a fuel controller. Here is one example (I am assuming this is compatible, you'd have to ask someone on an HHR forum) :

The Super AFC II (Air Flow Converter) is the industry standard for sub computer fuel control. The S-AFC II is designed to fine tune and "squeeze" power out of existing engine setups by allowing the user to modify the fuel curve with precision accuracy. Since the act of simply bolting on performance products does not make maximum horsepower, the S-AFC II allows the user to calibrate the fuel system in accordance with performance upgrades as they are installed. The AFC modifies the air flow meter/ pressure sensor signal voltage going to the factory ECU (Engine Control Unit) to change the amount of fuel injected

If I were "starting from scratch", this would be a serious option for me because I think it can also double as a ScanGauge.
