Find out your local laws on catalytic converters. For example, in PA you just need to visually have one on your car.
I know with my car when I got my headers it deleted my cat and I was just running test pipes, about a week prior to my inspection I got a hfc and welded it to my headers.
So think about that, I would probably get the cat before or at the same time as the headers, seeing as it's a fairly easy install, and the headers are a PITA and can be pretty expensive if you don't do it yourself.
Other than that it looks about right, get the car breathing better and have some fun!
