Basically I need to know what "aluminized" means. When I am all done my goal is to paint my exhaust system with a high temp paint.

Aluminized steel pipe has been hot-dip coated on both sides with aluminium-silicon alloy. It makes it more rust resistant. I used it for my exhaust pipes. I roughed up the surfaces of my pipes and mufflers with scotchbrite and painted it all with Eastwood exhaust paint. It has held up rather well over the years.
