Average MPG in your Monte SS?

I don't know where you live or your driving habits, but when the colder weather comes, your MPGs drop down. Not only does the gas have additives in it and the MPG isn't great from that, but usually someone will warm up their car. Also the air is pretty dense in the winter and your PCM commands more fuel because there is more air.
Overall you have done some great preventative maintenance. Keep an eye on everything. I would do the fuel filter, just because it was probably never done, and it's easy on these cars if the nuts aren't rusted up.

Glad to hear you were able to replace it. 
If you want you can also buy a can of seafoam to run through the gas tank. I wouldn't use much else besides seafoam though.

If you choose to, recommended if your oil change is within 250 miles.

Should I just start off by adding the seafoam into my gas tank? I've used it before on my thunderbird by adding through a vacum line and gas tank, but I see that you can add through a line on the supercharger too? Will it eventually cycle through everything once I add through the gas tank?

When you run seafoam through a vacuum line it's to help clean carbon from the intake ports and combustion chambers. Putting it in the fuel tank helps to clean the fuel system. Putting it in the oil helps to clean sludge and deposits from the crankcase and internal parts. I've read on another forum where some people give their vehicle a triple shot of seafoam. They put it in the oil and fuel, then run it through the vacuum line after putting a couple hundred miles on the car. Then they change the oil and install new spark plugs.
